This is a unused base plug-in that was for the BC-746 tuning unit. This has been in storage since the early 1940's. This is left over from the production of
the tuning unit that was used with the WW2 vintage BC-746 Early Pogo-Stick SCR-511 military radio. This was never used, wires or components were never attached or soldered. This has a dual FT-243 crystal socket that can be removed by drilling one rivet that is in the center. It then can be attached to you're project using one screw and nut. The complete tuning unit that is in the picture is not included. I just added that picture so you could see what a complete unit looks like. This auction is just for one unused base unit.
