A wonderful example of a double valve demonstration vacuum pump with brass and mahogany columns, decorative finials, and the raised larger plate supported columns, with a smaller one to the rear, signed on the engraved plate by Ladd, Penton place, Walworth
The brass work with the original lacquer and some of the original accessories are even signed as well.
These include a syphon gauge, a Magdeburg sphere, a glass blub with valve and a hand pump.
All contained in an oak traveling case which explains the fantastic original condition the instrument is in.
Ladd is listed working in the mid 19th century although this model is the same as the ones made by Adams in the 18th century .
