Found this in my parts selection. I don't know if it's a specific radio part or an aftermarket item. Almost looks like some sort of channel board, but I'm just guessing. I have no information or paperwork I can find.
Kind of looks like a signal generator for a sideband radio. If you triple the crystal frequencies you'll get about a 3kc offset between them in the 33 MHz range. No idea what radio it would be out of, though.
