A three draw telescope measuring 38 cms closed and 115 cms fully extended with a main lens diameter of 42mm, signed on the second draw, ‘Richardson, London’, and additionally engraved ‘ Adjustment for Greater Magnifying Power. For Day or Night’. The additional pancratic draw tube, marked ‘A’ on the collar can be brought to use by a small turn and pull to the tube. The benefit of a pancratic eye piece was found circa 1800 by adding an extra draw tube to a telescope, the claim to uniqueness is explained on the label to the inside of the case lid, which claims it “The telescope will then be increased in magnifying power nearly double”.
The back collar of the telescope is finely engraved, ‘IMPROVED TELESCOPE’.
An unusual telescope from the early 1800’s, very clear to look through with all original lenses, free of dents or otherwise, and contained in original wooden case.
Ask the Dealer
I live in Lancashire (U.K.) and have been a dealer and collector of scientific and nautical instruments for a number of years. My stock has included some fine items from museums and colleges, which were surplus to their requirements. I occasionally purchase some interesting items from abroad, having established some reliable sources.
