you would spec it if it was going to an already existing group of   r-388s!

The  question would be why after 55 would any purchasing agent spec a R-388 
when  the R-390 was available? Other then purchasing request that were in 
the  pipeline and delayed or specification for a project that was written 
before  the introduction of the R-390?
The other question is what was the intended  role of the 51J and later the 
51S receivers? Being at the time of their  production the R-390 were 
available, where the J and S receivers intended as  lower cost alternatives? Or 
because of their more friendly operator interface  and incorporation of SSB on 
the 51S1 intended as a intelligence gathering  receiver? The 51S1 and later 
651S1 were used a lot at  NSA

Well, the Signal Corps evidently acquired over 12,000  R-388's in a dozen 
contracts (most in 1950-54 contracts with some as late as  1962).
It is common to see them with field changes and MWO markings. So it  seems 
somebody must have been using them somewhere - maybe they gave them all  to 
the Air  Force?

The  GRC-26A, -26B, and -26C models used R-388's (and BC-610) beginning in 
1953.  The D model used the R-390 (and T-368) with production beginning in 
1961  according to this interesting  page:
