Do you know, or have you done the research on the SX-73 / R-274 to find 
out what the A, B, C and D models represented?

As Todd pointed out, the R-274 was the nomenclature for 'a' receiver.  
The SX-73 was one, and the SP-600 was the other.

As near as I have been able to figure out, the R-274-C/FRR was the 
SP-600.  I've never seen an 'A', or 'B', and I -have- a D.  Unless 
they're counting the non-designated models as 'A' models.

I'd simply like to find out more history on the contract.

Bah... as long as the damn thing works, I really don't care -what- it 
looks like!

I would *still* like to know where other SX-73 versions of the R-274's are.
