Signed'Berge London, Late Ramsden' on the first draw, this 3 draw midshipmans telescope dates to the beginning of the 19th century when Matthew Berge took over the business of Jesse Ramsden who died in 1800, and Berge signed his telescopes Late Ramsden till 1805, so this can be dated quite accurately. The mahogany barrel does have a number of splits which have been stabilised by internal glueing, but the brass draw tubes are dent free and still have a smooth draw action. It measures 29" extended, 9.5" closed with a 40mm diameter objective lens and although the image is a little dull it is well focused and still very much useable.
No brass end cap but the eyepiece is also protected by an external dust cover built into the cup, and the telescope disassembles fully for access to the interior lenses which are generally good, although there is a hairline crack on the outer eyepiece lens see last photo, but does not affect the viewed image in any way. This is a 200 year old telescope which is not only functional despite some imperfections, but signed by a renowned instrument maker. Please study the photos as they are part of the description, and I will be happy to answer any questions if I can. Please see my other auctions for more interesting items.
