This is a unused ww2 vintage 5 gang air variable capacitor. This capacitor has parts attached to it. The parts can be easy removed, I left attached for buyer may be able to use. This is dirty due to poor storage since the mid 1940's. The larger two gangs measure aprox 65 to 575 pf and 110 to 620 pf. These may be a little different because of small trimmer capacitors connected in parallel. I have many of these and they all measure about the same. The center small gang measures 19 to 34 pf. This has the larger 3/8 inch diameter shaft.
