This is a unused ww2 vintage military 3 gang air variable capacitor. This has wires attached to it, these can be easy removed. This was well packed since the mid 1940's so it is in very good condition for it's age. The gangs measure 16 to 555 pf, 15 to 423 pf, and 18 to 427 pf. This is a very sturdy well made capacitor for a WW2 vintage military radio. This has the larger 3/8 inch diameter shaft.
