Ref. 1851

An extremely rare mahogany cased mountain mercury barometer by Thomas Rubergall of Coventry Street  LONDON circa 1820. The barometer is divided from 23.3 inches of mercury to 32 inches. The barometer supported on a gimbal held within the tripod stand. The whole folds down to carry within the three legs of the tripod. There is a thermometer inlaid into the stem (replaced) The whole has undergone skilled restoration. It is in working order although there is no vernier. At the time of restoration much research was carried out but no similar barometer is known of by this maker. It is probably unique and would make an exceptional piece for a mountaineering collector  or a barometer enthusiast. (Price On application) Delivery world wide by arrangement
