An early 18th century style burr walnut and brass mounted siphon-tube barometer after Thomas Tompion, the silvered dial signed 'Tompion London' , the recording pointers operated by a pair of rack and pinion knobs above two silvered calendar dials registering the date and month, the case with a Doric pilaster and surmounted by a flaming brass finial, second half 20th century, 107.6cm high.

This barometer is a faithful copy of the siphon-tube barometer in the Royal Collection at Hampton Court Palace supplied by Thomas Tompion. The original barometer is discussed in Nicholas Goodison, English Barometers 1660-1860, pl. 140-142.
