I found a couple 115 pf, one with a shaft and a single hole mounting or
chassis mounting. The marks on the insulator say 100 pf but the rotor
plates aren't centered between the stator plates. Hits 75 pf about 1/3
rd turn of the shaft.
I could send it north with WB0LJC on Sunday or N0UK. Its been in my
collection a long time, I don't know what its worth. Maybe look at Fair
Radio, most of theirs are marked sold out.
