E.F. Johnson Co. Model 100ED30 dual section air variable capacitor. With the plates fully meshed each section measures just over 100 picofarads on the el-cheapo component tester.
It’s in fair condition, with a little rust on some of the steel hardware. I would recommend a good cleaning before putting the kilo-volts across the plates.
Price does not include shipping. I ship only to the USA and maybe Canada.
