The BC-434 is the remote control head for the SCR-269 Radio Compass Receiver system. The system was used on large aircraft, including B-17, B-24, C-47, et al. Typically, two BC-434's were used. On the B-17, one was installed at the navigator's station and the other was on the ceiling of the flight deck along with the command radio control heads. Have a look at this web site for lots of detailed info on the SCR-269 system and photos of its parts:

I couldn't find anything on the BC-AO-232.
Cheers!
