[Milsurplus] Navy Collins R-388A / 51J-4 update

[Nick England]

FWIW I just acquired a copy of the Navy manual for the R-388A. It is a govt.
printing office reprint of the 1960 (8th edition) 51J-4 manual with the
following on the cover and title pages:
NAVSHIPS 92324
0967-994-9010
Formerly 0280-301-1001
COMMUNICATIONS RECEIVER 51J-4
NAVY MODEL R-388A/URR

The schematic says "U.S. Government Printing Office 1971-714-005/2545" and
the back page says "U.S. Government Printing Office 1974-603-013/225" - yep
a 1974 date code!

beyond this I don't see anything to distinguish it from a Collins manual.

cheers,
