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?
