Unconventional and rather primitive air pump with a large-diameter barrel. The piston is operated by means of a rack and a handle fitted with a pinion. The plate supports a bell-jar with a ground-glass stopper. The instrument bears the inscription "Filippo et Haveri Fratelli De Dranchy," makers about whom we have no information. Provenance: Lorraine collections.
