[R-390] Top and bottom covers-Why?

[Raymond Cote]

I've been lurking to see if anyone would give a hint on what the different plate are that is presently being discussed. So, what and where are the Utah  and any other "named" plates?  I have every Collins radios from 51J3 on up and have not heard of these names used. No I don't have manuals available or I'd look it up myself. 
Anyone care to explain?
