My father-in-law, W9OIB (SK) gave me a couple of Jennings Radio vacuum
capacitors several years ago. According to Google, they are 100 pf
units. (They measure about 65 pf.)

Jennings Technology no longer makes these particular capacitors, and
they never responded to an email I sent them a while back. Current
Jennings Technology capacitors with similar dimensions (6.5"L x 2.5"D)
are rated at 32 KV peak test voltage, 25 KV working voltage, and 87 A
working current.

The devices are labeled "VCC-100 Jennings Radio" on the glass, and the
copper electrodes are hand engraved "VCC-100 225-30" on one and
"VCC-100 225-4" on the other.

I'm not going to use these and would like to put them up on eBay. To
do that, I would want to be able to list their correct specifications.
Can anyone on the group tell me what their specs are supposed to be?

Thanks,
