A small, taper barrelled, leather covered (on wood) single draw telescope, signed, ‘J. Long, Dover’.
Fully extended it measures 18.5″ and 14″ closed, with a 32mm triple main lens diameter.
It gives an excellent, crisp image when viewed.
Quite rare, as marine telescopes were usually much larger in size.
There were several makers with the name ‘J. Long’ from 1799 – 1846 in the London area. The telescope was more than likely to have been retailed in the port of Dover.
Mounted on a later wooden display stand.
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.
