[ARC5] Looks Very Interesting

Mike,

Studying the front quarter view photographs of the R-24/ARC-5 and the 
C-131/AR mounted on the front of an ARA or AN/ARC-5 communications receiver, it 
appears that the adaptor plate mounted to the front of the receiver in place 
of the tuning dial would just miss the antenna selector switch cover.  So 
you could probably mount the C-131 on an R-24.  Or for that matter, an R-23.

However, there is no known evidence that they ever did.
