Neo Classical English Georgian double-barrelled mechanical vacuum air pump, circa 1815. Two tapered pillar construction reminiscent of the Parthenon, the shaped mahogany pediment held in place with two Adam Finials. Demonstrating in a vacuum, the silence of a ringing bell, a feather dropping at the same speed as a lead weight, and something about canaries. All in excellent condition, retaining original lacquer to the brass and patinated polished surface to the mahogany.
Good tight motions to the rack and pinion action, a little tinkering and youd be impressing your friends with a show. Rectangular base 13,1/4 x 10 or 337mm x 254mm Weight 9.8kg.
