The "Sheraton shell" pattern of decoration in dial barometers, with two inlays of conch shells and two of stylized flowers, was prominent from about 1805 to about 1830 in England.
This is a nice example in very good condition, with good color and inlays. The case is outlined with ebony and boxwood stringing and has a recently polished finish. Restoration is minimal, consisting of minor repairs to the stringing.
Francis Gally is listed as practicing in Sheffield between 1805 and 1825. This barometer was made 1820-1825.
