[Milsurplus] R-388/51J3 Difference

[radioman390 at cs.com]

If memory serves correctly, the mil version was tropicalized with yellow shellac.
Also the radio came out as 51J, 51J2, and then 51J3 which was the 388/URR.

The 388A/URR had mechanical filters added (an upgrade kit was available) and sold commercially as a 51J4

Can't think of too much else.

Others have comments?
