Signed on the first draw in script, ‘Watts, Poole. Day or Night’.
There is no maker recorded with this name in Poole, Dorset so it may well be a retailers name.
By design, certainly circa 1850, maybe a little earlier.
Measuring 16 inches collapsed and 35.5 inches fully drawn with dust sliders to each end, with an objective lens of 1.5 inches. Damage free, no dents or cracks. It gives an excellent, sharp image when viewed.
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.
