This is an extremely rare variable condenser dating back to the time of Marconi. It appears in the Manhattan Supply Company catalog and is described as follows. This condenser has a minimum capacity of about .0005 M.F. and a maximum capacity of .003 M.F. The change of capacity is gradual. Fitted with graduated scale.
