[R-390] R-390A Manufacturer ID help

[Glenn Little WB4UIV]

If this radio is like most R-390A receivers, it went through depot for 
repair.
At this point all of the modules were pulled and they were cleaned, 
repaired and updated along with all the others in depot at that time.
When the receiver was reassembled, any module was fair game for the 
reassembly regardless of who made it.
So, unless you have a receiver that has never been through depot, or 
someone along the line ensured that all modules were made by the same 
company, the receiver is a hybrid of modules.
Any tag should work.
IIRC there were two tag sizes.
I may be confusing R-390 and R-390A.

There is nothing on the rear panel that indicates the source, the PTO is a Collins version, but that may have been changed in the past.  It works great, but looks rough and looks as it was dropped on it’s right-rear panel at one time.  Plan to attempt to refinish the front panel someday and if I can ID the maker, will get a tag from Fair Radio.  It is currently rack mounted with a nice R-388 and a National HRO-5TA-1.
