Possibly the lenses from the wreck, number 3, might help with a current re-build project on a Ramsden scope! 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. It’s currently a favourite item in the collection, listed as #226. Provenance: Descended in the family of Captain Theodore Corner and used at Corner’s Wharf in Baltimore by the shipping firm James Corner & Son’s in the mid 19th century. When closed it is only 11.5”. All of these are for sale, to someone who wants to take them further. In an antique shop this would be put on sale for £2000+, but the real sale value is probably half that. The Maritime Heritage Association of Australia in 1991 advised that Helena Mena’s hull was painted black with a yellow-gold sheer line. 1892: London to Freemantle and back, as above. A similar design of telescope, but one which uses the Schyrle-Huygens eyepiece system with 4 lenses in the first draw, and dates from around 1850, is the John Hewitson unit described earlier. The tube is 43.5 inches long. This draw caries the quoted engraving, and a line to show the typical focus point. Sometimes you have to take a punt. First page of the letter from Frank Musgrave. 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. Inside, the internal bore is straight half way down the tube at the eyepiece end, and then slowly increases towards the objective lens position. It was seen once before in a James Chapman octagonal telescope in my collection, but this one really did date from the late 1700s. Unusually, this telescope brass responded well to machine polishing and buffing. This instrument is now know as a divided object-glass micrometer, and was one of the most useful … It was described as “possible Navel”, which maybe described the shape of the eyepiece, rather than the intended use. For anyone interested in further information about Ted Corner and his Baltimore Company, or in researching this telescope further, please make contact with the owner via this website. 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. 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. The different feature here is that the scope is all brass in construction, possibly reducing the maximum OD of the unit, compared to a mahogany barrel – it is about 1.25” OD round the Barrel, but 1.375” where the brass raised around the objective area. The lenses used do not appear to be incorrect in any way, so they are all there, but as the saying goes, “not necessarily in the right order”. 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. Antique Telescope, Dollond London, Terrestrial Four-Draw Refractor, circa 1800 Located in Hele, Devon, GB This is an antique telescope by Dollond dating to the early 19th century, a four-draw Scope suitable for terrestrial or astronomical use, circa 1800. 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. The scope is exceptional in its unwieldy-ness. 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. 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. Based in Baltimore, James Corner & Sons employed all six sons of James Corner at various times, but possibly Ted’s main role was as a captain of one or other of their ships. Here is the Auctioneers description: "Dollond 4-inch Brass Refracting Telescope, London, c. 1825, Bywater & Co., 58-in. 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. This might indeed have been used to give some resistance to pulling the draw right out, and it could be squashed through in the assembly of the unit – there’s no other way of getting it inserted in practice. At the eyepiece end, the barrel is 43mm across the flats, outside, and at the objective end, this measurement is 48mm. One of the few ships of this style that still exists is the tea clipper the Cutty Sark, now moored in Greenwich, which was built in 1869. Those telescopes were labelled G & C Dixey. The sunshade is again brass, and this has a push on brass end cover/end-cap. The internal bore is evenly tapered, all the way, presumably using a wood boring tool, or chisel. Second, the draw is fairly tight in the barrel (still, after 220 years), so the lack of an end stop does not let the brass section slip out when holding the telescope. Seller 99.8% positive. The faceplate at the eye end is marked “DOLLOND * LONDON.” For storage, the telescope fits into a mahogany box with a hinged lid. The objective lens, however, does have a standard slide for protection. The major difference in the Dollond is that the lens mounting positions in the first draw are at either end of the draw, and then at two places where the draw is split to allow access to these lenses. 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. Maybe: This postscript was added 2020 – as reading thru the website I realised often the reader’s comments on these articles are not visible! So, a lovely telescope, missing lens 2. $ 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. The objective housing has had a couple of sharp cuts from knocks, but the lens screws in straight and smoothly. It looks perfect, but the eyepiece sliding lens protector is missing. About 1% of these are key chains. Then there are only three lenses in the first draw, making up the eyepiece assembly. The missing bit is the objective lens, and carrier: it was screwed into the end of the barrel, but has either been knocked off, or fallen off, either overboard, or otherwise it was lost. The single draw has three screwed splits, but the second split going towards the eyepiece has a cartridge containing two separated lenses: overall there are five lenses in this single draw, which pulls straight out of the barrel. The barrel is 24.5” long, including the brass end fittings. Not easy to use to lift up and follow aeroplanes. The draw tube itself, without the eyepiece end, is 9” long, so occupies the whole barrel when closed up. 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. Pretty useless really, unless you have the estate to view, but they were popular in the 18th and 19th Centuries. Accession Number 297, acquired December 2016. in order for this application to display correctly. In fact one of the coaling stops was at a location/town called ‘Mirzapur’, close to Benares. Ref #313 was bought to replace #193, and is complete with end cap and slider in the eyepiece, and with original screws in the barrel. Conceived by Kitchiner to increase magnification of the standard telescope, the manufacture of his invention seems to have been entirely gifted to The Dollond family whose optical work Kitchiner is known to have admired. This Dollond is engraved ‘Dollond London x15’, all in capitals with the angular, heart shaped “O” letters. Lacking a proper objective carrier, the interim plan is to use an objective doublet from a (trashed/squashed) Dollond WW1 Scout Regiment scope as the objective, right size/focal length, to show the old girl working (See top picture). £27.00. 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.
