One of those mystery boxes is probably a BC-**-183 which was a BFO
used with the BC-A*-179, -199 and -229 receivers for CW operation.
That would probably be the one that looks like a frequency meter since
it has a National dial - or mine does anyway.  The calibration charts
from which it could be tuned to the proper frequency would be in the
lid (which is missing from mine - anyone have an extra?).

This was pretty much the same setup used in the B-15 although the B-15
had significantly more space and I think had two receivers that, if I
remember right, were tuned with the same shaft.
