Not easy to use to lift up and follow aeroplanes. Ebay pic before: Then my pics after polishing! This was never used for anything other than a display item. And I apologize to ‘m***m’ who was the only other bidder who also thought like that – he only pushed the price up to £47.99. So let’s look at these other four multi-sided telescopes to see what emerges. main tube, ocular collar engraved "Dollond London/Sold thru Bywater & Co. Liverpool," mounting collar, and dual tapered… This cap holds the first lens cartridge in place, which is a push fit into the first draw. The other three lenses in the barrel are mounted at two screwed splits along the length, and the last is at the objective end of the draw, which pulls out freely, it is not retained in the barrel. He had owned and used the telescope since 1891, and he had it cleaned and re-covered (in Burma) to present it to his successor in Rangoon in 1932. I guess this was over-engineering, as many of the users of such a telescope would have found this piece of metal sticking out either hit them in the eye when the ship lurched to one side, or maybe was flipped out of the groove when knocked at any time. Possibly this split was caused when someone was hand-engraving his initials “E+P” on one of the flats, which remarkably is followed by “1781” which is presumably the date of this engraving work. The telescope is obviously very old. It is interesting to note that the design of this slider and shoulder was a Dollond Patent as well, described first in around 1780 apparently! Open, fully, it is 44”, or 1.22m. Maybe there is another place it would be more appreciated. View sold price and similar items: A Dollond London Telescope, Including Timber Case & Timber Stand, from Theodore Bruce on March 3, 0121 6:00 PM AEDT. “Dollond 4-inch Brass Refracting Telescope, London, c. 1825, Bywater & Co., 58-in. The two draws are almost interchangeable between #59 and this one, which is reference #189. To me, the split draw does indicate an early date of telescope, I estimate around 1800-1820. 1758 John Dollond obtained a patent on a compound lens for refracting telescopes which was free of both chromatic and spherical aberration. As can be seen from the pictures below, showing before and after photos of the brass cleaning, the leather sleeve on the wooden barrel has done its job, and protected the barrel, but has suffered significantly in doing so. $ This is maybe because of the substantial felt lined leather case that came with it. DOLLOND, LONDON, LATE NINETEENTH CENTURY 'DAY OR NIGHT' LACQUERED BRASS 3 DRAWER TELESCOPE, the main body with mahogany sleeve and slide hood, the ocular and objective lens with dust slides, 2 1/2" diameter x 33... [more like this] LONG GLASS - 19th c. leather covered, brass These included the Carrier Dove, the barque Huntington, bought by Ted Corner in 1854 and used as late as 1860, the Maria, and, all in 1859, the North Carolina, the Birchhead and the bark Seneca. She was then reported as bought by Norwegian owners at some time later, retained her name, but was quoted as being “reduced from ship to barque rig”. One area of slight separation between layers can be dealt with…. The single draw tube contains all the four eyepiece lenses, at the ends, and at the two joints in the tube itself. It would be even better to link the telescope to the Pepys family: Samuel was Chief Secretary to the Admiralty under both King Charles II and subsequently King James II, and so effectively in charge of the Navy. Starting as a 2nd Officer he progressed up the ranks to become Commodore. The scope described above looks to be a much later design, and in my opinion dates from the early part of the 1800s, maybe as late as 1840. Your web browser must have JavaScript enabled The lens assemblies are also unusual, complex, expensive to manufacture, and look a little “one-off”, as if built to fit, after the main outer parts had been finalised. A couple of hours of scraping removed the caked paint, down to some lovely looking mahogany, with a couple of splits along the length. So without a working solution it is only worth around £600: a new objective lens carrier without the lens would be around £200 – I’ve only ever seen one sold as a spare.. It is now in use on our decking in the back garden. The body is secured upon a solid brass 19.5 inch high tripod base with tapering shaft upon articulated claw feet. The two of them fell in love, but the ship owner did not like this, so offered to give the boy the ship, if he would sail away and never see his daughter again. £27.00. Ref #193 was complete, although one draw was stiff and the mahogany had a crack along the length, but it worked beautifully: this one was given away. I failed to go that high. The box itself is fitted with cut-outs to hold the telescope, and also contained a mounting bracket, which could possibly be fixed to a hand-rail or ship’s structure, which then had a pair of leather straps to hold the telescope in place in a cradle, at its balance point. 84 cm long (extended)… Show 9 … It would just look so much better. Overall length is 26” extended, with an 18.5” body: this is 2.5” diameter at the objective lens, which is held in place in a copper fitting that provides the joint between the telescope body and the sunshade. Then returned from San Fransisco to London, a journey that took them 186 days (round the Horn), of which the last 42 days were spent with limited food-stock, so they were eating only dry biscuit and tea “sans sugar, sans milk”. Then there are only three lenses in the first draw, making up the eyepiece assembly. and chemicals in Maryport(?). The eyepiece end of the main body tapers down over 3.5” to join to the 1.25” diameter single draw. Others, notably Chris Lord, have suggested that Schyrle three lens systems were used on telescopes well into the early part of the C19th: the construction of this scope does seem to bear that out, in that it would appear to be of the style of the early 1800s. There have been many well-made brass telescopes over the years, but those made by Dollond, London, Bardou & Son and D. McGregor & Co. are often thought to be among the most beautiful. Actually I’ve never seen one of these flaps in place on any telescope! The Oriana that went to Australia with emigrants in around 1894/5 with Frank Musgrave was built in Greenock by Scott & Co in 1864, was an iron barque with two decks, 1050 tons, 202 feet long and 33 foot beam. This is a composite image, the tubes are NOT bent! The Maritime Heritage Association of Australia in 1991 advised that Helena Mena’s hull was painted black with a yellow-gold sheer line. Gloria Clifton’s Directory of British Scientific Instrument Makers suggests John Bywater & Co was the trading name used by this firm between 1822 and 1831 only. The main barrel is covered in good quality soft leather, or maybe some other animal skin, light brown and dappled: this will later be shown to be a replacement in around 1930. Approx 5.5” of this draw is extended at the focus point, and there is a line scribed on the draw to show where to pull it out and stop. It follows good mechanical principles, and positions the mounting thread around 1” inside the tube that is the next larger on the scope. If the scope is used with this lens cover in place, but with the slider open, the diameter of the window opening onto the objective lens is only about 0.75”. The OD of the sunshade on this scope is 1.375”, and the barrel is 1.25”. The story from the Oriana Kro Inn at Nusfjord is from the same era, the Oriana was quoted as a three masted sailing ship from England. Then, under the shaped eyepiece there is a fifth lens, so I need to find out whether this was common, and when five lenses were used – it is possible this leads to an earlier than 1800 date. The search continues for a more suitable lens. At least I am of the opinion that this is better than equipped with the battered leather cover. This achromatic navigational telescope has a leather-covered barrel and a single brass draw tube. A picture of the figurehead from a similar freight ship of the late 1800s, also called the Oriana, can be found on the website of the Oriana Kro inn in Northern Norway, at Nusfjord, on the Lofloten Islands, www.nusfjord.no. A separate attachment point on the barrel is provided, presumably for a handle or rod to control the elevation of the scope, rotating round the axis of the mounting screws located onto the stanchion (See the top photo, next to, and on the left of the clamp). Family research accompanies the lot. 1894: A repeat, London to South Shields to Port Pirie, and Port Germain this time, then Port Augusta and home via Cape Horn. The scope was bought from a dealer in Littlehampton, West Sussex, in August 2017 – an Ebay Buy-it-Now item that was suddenly withdrawn, so I chased it. Up at the top of the river, across from Mandalay towards Imphal, became the main battle zone between the British and Indian armies and the Japanese troops: where both sides were hampered by extended jungle supply routes which used horse and mule trains. It has been possible to determine that “IGSN” is the India General Steam Navigation Company (established 1844), and similarly “Ganges SN Co” is probably the Ganges Steam Navigation Company. This was where my Dad was fighting. Those telescopes were labelled G & C Dixey. If I saw the machined groove at the end of this draw on a modern piece of equipment I would say it was designed for an ‘O-ring’. Both cartridges pictured have external threads on the bottom, to attach to the adjacent brass fittings. The body construction is unusual, with the tapered brass main body, and the stand is very ornate, as in pre-Victorian. main tube, ocular collar engraved “Dollond London/Sold thru Bywater & Co. … The engraving on the telescope says “DOLLOND * LONDON”, at the top, in capitals, and then underneath it adds “Sold Thru Bywater & Co, Liverpool”. This draw caries the quoted engraving, and a line to show the typical focus point. The East Croft was also an iron framed, wooden clad ship, around 1367grt, built in 1875 by Harland & Wolff at Belfast, for John Gambles, of Workington. The problem is that there is no other telescope with such a well documented history to compare it with, plus it is in excellent undamaged condition. The Hewitson scope is the smaller, second one down: this photograph shows my first three significant purchases, back in 1992. At its peak in the late 1920s, the IFC fleet was the largest fleet of river boats in the world, consisting of over 600 vessels carrying some 9 million passengers a year. He was Frank Musgrave, the retiring Commodore of the Irrawaddy Flotilla Company (IFC) in around 1932. A Marine Telescope by Dolland, c. 1840-1850, a single-draw achromatic refractor signed 'Dolland London Day or Night' in brass with mahogany barrel, objective stopped to 38mm, telescope 87cm extended, with associated tripod and mahogany case The internal bore is evenly tapered, all the way, presumably using a wood boring tool, or chisel. Great news: the barrel red mahogany is beautiful: it has some cracks, one of which is open, – it can easily be glued – but other old glue lines that protrude, etc, are coming off with sanding. Again the single draw pulls out of the barrel completely, just after the last lens in the eyepiece set of four, so the barrel has two screwed splits. His letter to James Bichard, enclosing the telescope pedigree, is a beautiful document, in black ink on IFC official paper: but, for Google, I will type it here, as a chronology, and show just a little in a scan. The single draw has a total length of 26”, and is approx. Having such an objective means that the close aperture inserted in the barrel would have been essential so as not to allow the outer edges of the objective to transmit light down to the eyepiece. The final downer was that mid way thru the auction bidders were advised “there are no lenses inside”. It looks like it was originally French polished and is oak. 1893: On the “Oriana”, described as an F.R. The eyepiece cap screws into the top of the first draw, but this has an integral long parallel section, 11mm long, that prevents the first draw pushing further into the barrel. So the ten sides are produced by planing down the round barrel into a series of flats – again the transition from one to the next is relatively smoothed over. See www.carrierdove.org for extensive further info. It’s very important to a collector to actually have an example of one of these multi-sided telescope designs in any collection, as they are some of the oldest, and in some ways most interesting. This one has the brass barrel covered in pseudo leather – which is probably real…. Then, in 1766, Frederick the Great instructed his London ambassador to buy two telescopes from Dollond's 'because they magnify extraordinarily the object'. This scope was bought in 1997 from the London Scientific Instrument Fair, from Swindon based Tim Collins, who had a Portobello Road stall in London as well: it is my reference 39. When opened up to focus the scope, the length is maybe 47”. Regrettably no info is available. Only Genuine Antique Dollond Telescope Approved for sale on www.sellingantiques.co.uk Maybe this was needed, because there is no end stop, the draw pulls right out: this is a characteristic of older telescopes, ie before 1800. The barrel is externally 10-sided, mahogany, with worn French polish. So it is a more conventional 4 lens system in the first draw. It works well, although the draw tube is stiff. The other fittings are also brass and include an objective lens cap, a pivoted eyepiece cover and a sliding sunshade. So the pictures here are for record to see where it gets to when treated with TLC. At the objective end, the lens aperture is 1”, and the glass is protected by a sliding cover. So it is basically used as a source of spare lenses. It is signed "Dolland, London, Day or Night" on the draw, with the eyecup to the right. A brass and mahogany single draw Captain's telescope, by Dollond, London, circa 1775, the brass tube above a faceted lower section, inscribed to the end cap 'Dollond / London'. Suitably sanded, the mahogany now (23/12) has two coats of polish, and is looking good. An’ the dawn comes up like thunder outer China ‘crost the Bay! Anyway this one came from Ebay as a “Buy it now” in March 2013, for £230, and is number 182. The sunshade is still present on the objective end. My understanding is that it was pretty old even then! To use a telescope that was made by Peter Dollond, in one of the first applications of his patent, 250 years ago, even though the eyepiece lenses inside are from one of his Dollond successors, is a real thrill. Carrier Dove was fast, in 1858, presumably on the return journey, Captain Corner sailed from Liverpool (UK) to Melbourne Australia in 78 days, and then on to Valparaiso in Chile in a near record 30 or 32 days (Wikipedia). This is a 3-draw Dollond with a wooden barrel, a medium sized telescope around 20” long when extended. Such slides are always difficult to polish – unfortunate here, because the objective cover slide, rather than the first draw, carries the maker’s name. This gave a much larger cargo hold capacity, without any large wooden cross beams. Plus it works beautifully. This has another engraving, stating “Sold by Bywater & Co, Liverpool”. Inside, the internal bore is straight half way down the tube at the eyepiece end, and then slowly increases towards the objective lens position. There are three screws needed at each end of the wooden barrel, and this scope has two of them, the original ones, present at each end. The Schyrle eyepiece system used in the third model is very unusual. East Croft spent 6 months transporting cargo, maybe coffee or minerals, between Acajulta and San Fransisco. So the decision is whether to cut the leather off and re-polish the wood, after gluing up any/all of the cracks! 3rd from top: Late 18th century four draw telescope with shagreen body signed DOLLOND, LONDON. George Dollond, (born Jan. 25, 1774, London, Eng.—died May 13, 1852, London), British optician who invented a number of precision instruments used in astronomy, geodesy, and navigation.. The faceplate at the eye end is marked “DOLLOND * LONDON.” For storage, the telescope fits into a mahogany box with a hinged lid. The following pics show the before and after condition, in as much detail as the Ebay seller’s pics gave -I’m sorry I didn’t take my own “before” pics! The whole original eyepiece lens assembly was difficult to understand, and not of a type seen before, so a replacement sleeve with two sets of lenses in barrels (the first draw from a later Dollond scope) was inserted into this P Dollond telescope single draw (it was an interference fit) and secured in position with the flat end eyepiece cover (from a JH Steward tapered body scope). John Dollond preferred this device to be used with a reflecting telescope, however his son soon adapted the device so it could also be used with a refracting telescope. He gave the telescope with its pedigree to James Bichard, when he took over the role of Commodore of the IFC in the Summer of 1932. The four lenses are shown as the bottom row, they go inside the ends of the tubing sections. DOLLOND London 1920 Marine Collectible Décor Nautical Spyglass Antique Mounted Solid Brass 15 Inch Pirate Telescope with Wooden and Branded corrugate Box. The draw is engraved with the normal “Dollond London” and “Day or Night”, but also has an elaborate explanation as to why it was presented to Captain G.V. This is a couple of coats of French polish into completion, and the telescope is looking good. The engraving on the left of the first draw is shallow, but it is “Dollond London”; “Day or Night”; “5009”. The scope is exceptional in its unwieldy-ness. The outside of the barrel, instead of being leather covered, which became the normal covering later, is brass, with the surface scratched in a fairly irregular pattern, then coloured in a brown shade, to simulate the appearance of wood. In fact one of the coaling stops was at a location/town called ‘Mirzapur’, close to Benares. The sort of scope that would be in a bay window in a library, so that the reader can look out and easily use it to investigate the activities of a passing deer or fox on the estate, or see who in the hunt is in the lead. From there the internal diameter increases towards the single draw and the eyepiece, so mirrors the effective reverse taper seen on the outside. Rangoon Harbour, showing several paddle steamers. There are then four further lines obvious on the draw tube, and these are all screw threads joining short tube sections. Regrettably the winning bid was over £100, just for the brass assembly! All with three draws, they are the shortest units that can perform reasonably well, without going as far as having a multi-draw construction, a design that gets heavier and larger in diameter in the pocket. Another longer mahogany 10-sided unit, similar to #59, but here the barrel is visibly tapered in the normal way, with the larger diameter at the objective lens. Throughout most of his life, he worked for the family firm of mathematical instrument makers, assuming full control after the retirement in 1819 of his uncle Peter Dollond. An interesting feature of this design is that the sliders mounting each draw are sized very close, making a good seal on the outside of the smaller tube. Competitors produced telescopes labeled Dolland as counterfeits and to avoid legal issues. hree eyepiece lenses, the first, third and fourth were present. So its maybe later in date than the design might indicate. It was acquired in August 2017, as ref #313, and is frankly the same as two previous purchases, those with Accession numbers #193 and #98. This effectively set back the Japanese advance through Burma, as other road transport communications were very limited,and the alternative was to trek through the jungle. Note: This telescope was put up for Auction at Skinner Auctioneers and Appraisers in Maryland on 27th October 2017, estimated at only $500! The old rusty screws (that were too big for the holes, see the top photo) will be replaced with brass ones at least. This rare vintage Dollond 1.25" brass eyepiece for astronomical telescopes, is in very nice condition. The largest, third draw is 1.375”, compared to the Dixey at 1”. The design is classic for a medium sized scope, very similar to the early Ramsdens or the Watkins & Hill described on the last page – although earlier than that one, dating from between 1810 and 1820. This telescope has double the magnification of the Dollond quoted above. DOLLOND London 1920 Marine Collectible D?cor Nautical Spyglass Antique Mounted Solid Brass 15 Inch Pirate Telescope with wooden box. Possibly the 5009 (construction number?) This could be down to the larger diameter lenses used in the eyepiece section: the three draws are altogether larger diameter and feel much stronger than those in the Dixey. 1889-1891: In the Royal Victoria Yacht Club at Ryde (which was established as different to the above in that it allowed ladies to enter the premises). The main barrel is shown below! Around the main barrel there is a clamp ring, whose position looks to be adjustable, but would appear to be associated with a similar large screw hole in the barrel. Here though the draw has the words Gaitskill, maker, Wapping, London engraved on the very first section of the draw tube, on the left, ie with the ‘G’ of ‘Gaitskill’ adjacent to the eyepiece, which is the early style. In the photos you will see that the eyepiece terminates in a flat ended brass fitting with a female thread onto the single draw. Maybe: This postscript was added 2020 – as reading thru the website I realised often the reader’s comments on these articles are not visible! The eyepiece itself has a groove across the top, which would have taken a brass cover, held in place by a small screw that located in the cut-out visible. It would find best use overlooking a shipping channel, screwed to a balcony rail. That was my impression. The barrel is interesting, in that the inside bore is circular, and the outside is cut with ten sides, but the transition between each of the sides is very much smoothed over, consistently along the 24.5” length. The way I define a Library telescope is that it is mounted on a stand that is intended for being positioned on a table, such that the user can sit in a chair and look through the telescope when it is pointing horizontally. There is then an eyepiece lens almost proud of the rear end of the telescope, totally unprotected, and there is no evidence of an earlier cover being attached here to protect it. Restored to being in working order with a new lens added, but this lens probably is the reason for the limited field of view/relatively small image diameter. A collection of vintage nautical and army (terrestrial) telescopes, Three small telescopes: Dollond, Dixey, and A. N. Other. Offers over GBP £7000 will be considered! But it shows you can still find gems like this for reasonable prices. It was quoted as circa 1790. So since the screws here do not look original, these were taken pout to inspect the lens. Similar machining on the end is not a groove, but a raised rim on a section of the draw tube which has a smaller diameter than the rest of the tube, so maybe it was wrapped in some material or felt to push through and make an end stop. The construction of this one used eight identical strips of mahogany, about 7/8” wide, with the inner edges filed down, so that they can be glued together in an octagon. Another interesting and traceable telescope has been described by a correspondent in Maryland, USA, who has just resurrected it from her brother’s basement after 30 years in storage. It looks like Dollond would not have had a leather cover: maybe this was added to protect the barrel, as there do look to be several cracks in the wood, under the leather. The apparent colour difference is possibly that only the centre section is ground to the correct radius to nestle into the second lens, and where the two do not touch gives an impression of a coating, because of the different reflectivity. The telescope actually has a split which extends maybe a third of the way along the barrel, which follows the grain and moves from one flat side to the next. Whether I would trust that on a ship at sea I doubt, but it might work on an Irrawaddy paddle steamer. She was commanded first by Capt John Tayler Rimmer, until his retirement in 1895. It is a little unusual in that it has a brass barrel, rather than a wooden one, and this is coated with a veneer or similar covering. It was then believed to have sailed under the British flag until 1897, with D. Connack as Master and Trinder, Anderson & Co as the owners: these must have been Musgrave’s bosses. This unit is constructed from a single length of wood, drilled out with a smooth straight bore. The three lenses in the Schyrle eyepiece design. Argles. So keep on looking! The objective lens is original, and is a dual element construction, with each of the two lenses being considerably thicker than is seen in later telescopes. This scope is of a classic design, with two lens cartridges at either end of the first draw, each with two lenses in the Schyrle-Huygens eyepiece arrangement, which is the format generally adopted for telescopes after 1800. Rudyard Kipling writes about the IFC “Flotilla” in his poem “Mandalay”, which was first published in 1892: By the old Moulmein Pagoda, lookin’ lazy at the sea. About 1% of these are key chains. The eyepiece shape maybe pushes you to an early date too. Unpolished, as received: two joints in the draw, labelled Dollond, with bash marks! Create a free website or blog at WordPress.com.

The box was named on the outside, all in capitals as: Inside there are several pictures (modern, colour pictures) of sailing ships taken from, for example, the paintings by J.Spurling of the 1866 tea clipper races, specifically of the ships Ariel, and Taeping. 1897-1932: After this obviously Musgrave had a career rethink, and moved in June 1897 to work for the Irrawaddy Flotilla Company in Rangoon, Burma (now Myanmar). All of these are for sale, to someone who wants to take them further. If you look in the distance there is no colour fringing evident, but looking at the sky and angling to see the edge, maybe this does look yellowed. away with it.
