[Boatanchors] HELP IDENTIFYING A VARIABLE CAP?

[k0dan]

This is probably better suited for one of the Heathkit forums, but since I
don't subscribe there, I am hoping my inquiry won't impose on this group,
and some knowledgeable soul will be able to help.

I am trying to find out the specs for a variable capacitor I have. It is
reportedly for an SB220, the nomenclature on it says 26-145. The box it's in
says 255-C129-OC. Physically, the cap measures 6"x1.5"x1.5".

I downloaded the SB200, SB220, SB-221, etc., manuals from the BAMA site, and
the manuals are not consistent in their parts list versus values shown on
schematics.

Best I can find for 26-145 is that it's a loading cap for an SB220???
But...the schematic refers to a different part number, and I'm not sure the
values on the schematic actually match the component in question.

I don't have any Heath equipment, but am hoping to use this cap in another
project. But: it's specs? Can anyone help me identify it, capacitance range,
breakdown voltage?

Thanks and 73
