[R-390] Engraved front panels on R-390(non A)

[Aidehua@aol.com]

To my knowledge, all of the R-390 (non A) were silk-screened 
(Collins/Motorola).  Even the early R390A's were silk-screened 
(Collins/Motorola).  I think the engraving started with Capehart, Imperial or 
Stewart Warner in the late 50's.  Hence forth, they were all 
engraved....That's my story and I'm sticking to it...
