I need to replace small knurled knobs and SO-239 bulkhead connectors on some WWII avionics panels. Is there a good source for these?

Try McMaster Carr for knobs of all sorts

Suggestion: post photos of the knobs and SO-239s you're looking for. There were dozens of different styles and sizes of knurled knobs and several styles of SO-239s used during that time period.

(I may be able to help with the SO-239s, but I need to know what you're looking for).
