Electrostatic Induction Machine
This is a 19th century 2 plate Whimshurst-Pattern Machine. The black laquered cast iron base has a copper
plaque stamped with the makers mark... "MC". I believe this instrument is French.
The Vulcanite plates have foil inserts. This device very showy and complete with no cracks or warpage.
Note that the discharge tube is not included and is for display only...$950
