A very good four draw brass portable telescope measuring 42.5″ (108 cms) fully open and 12″ (30cms) closed, with a main lens diameter of 2″ (5 cms). It clamps onto the tripod on the fourth draw and stands at a height of 15.75″ (40 cms). The column of the tripod unscrews from the stand and is re-fitted in a reverse position for storage within the case. The column can also be unscrewed to reveal a steel corkscrew which the user has an option of attaching to a fence post, or similar, when outdoors.
The telescope gives excellent, clear views. The mahogany barrel is free of cracks, the lenses are all damage free, the brasswork retaining all original lacquer though there are obvious usage marks.
Signed ‘Rothwell, Bacup’, to the first draw. Bacup is a small village in Lancashire and is approximately 15 miles from Manchester. Records show an instrument maker / retailer by the name of ‘Rothwell’ (christian name unknown, not recorded) in Manchester from 1780 – 1820.
The telescope is very similar in construction, appearance and quality to that of Dollond, circa 1800.
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.
