An exceptionally rare and possibly unique 18th century wheel barometer.
The 8½" diameter silvered brass scale calibrated from 28" to 31" with weather indications shown in the earlier position on the outer edge of the dial. The centre of the dial very well engraved with a star burst and makers name. The finely cut brass set hand controlled from the base of the barometer using an internal cogged wheel and spindle mechanism. A very rare feature. Also with blued steel indicator hand. The whole dial enclosed within a glazed brass concave bezel. The long and offset silvered brass thermometer scale with extreme temperatures shown from -20º to 210º Fahrenheit. The mahogany case of a most unusual design with cross-grained sides, boxwood edge inlay and herringboned mahogany veneer to the front. This type of veneer is usually only found on stick barometers of this period.
