That sounds like a mica transmitting capacitor. It probably has a voltage
rating of a few thousand volts AC. It could be used in tube coil service,
which is a use fairly close to what it might have been originally
intended for. (radio transmitter). Mica has outstanding rf
characteristics-- the only problem is that the plates are often
vapor-deposited, so use in a conventional disruptive-discharge coil would
erode them.
I know that's not much help--- but... so?
