[ARC5] C-43/ARC-5

Hello folks,
  Maybe I missed this in past discussions but my curiosity begs a  
question:

The subject is currently up for auction on the usuall block.It is made 
by Western Electric and has SCR-274N dials yet bares the nomenclature 
of an AN/ARC-5 component.

Were some components interchangeable between services? (I know that 
most all receiver related components were interchangeable physicaly).
