Single draw, taper barrelled marine telescope, silver plated on copper, signed on the draw tube: ‘Worthington & Allan’. Measuring 31″ fully drawn and 25.5″ collapsed with dust slider to the eye-piece and lens cap over the 1 & 5/8″ green tinted objective. Retaining the original leather covering to the wooden barrel, including two carrying loops (one split), it gives an excellent image when viewing, the lenses damage free.
Worthington & Allan worked 1821 – 1834, took over from Mathew Berge and acquired Ramsdens dividing engine.
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.
