[Milsurplus] Module identification

[Robert Downs]

They could well be out of RBM  or  RBS.  It is too many decades since I last
saw the insides of one of those.  But they are not (as someone else wrote)
out of any one of the two  groups of models of BC-224 or three groups of
models of BC-348.  I have a bunch of those - somewhere.

Glenn, they look rather similar to the bandswitching modules used in an RBS
receiver from WW2. Possibly for an RBM, as they look similar. They come out
only after the long bandswitching shaft has been removed. There's one for RF
in, RF out, and the oscillator. And the small trimmers on the sides have a
tendency to short out due to weak springs holding them together.

Can anyone tell me what radio these RF modules are from?
Pictures are attached.
