[MRCG] Help identify crystal container box

[Tim]

OK,,,It's kind of interesting that the transmitters would have different T
numbers between voltage options.  Just a simple jumper change
differentiates them...  Keeping it simple for the troops I guess....
The newer Collins 618F-1A VHF transceivers are also identical between the
12/24 volt versions - just move jumpers.  But Collins had a neat idea - a
double-sided ID nameplate.  Just flip it over when you change the jumpers,
it indicates the primary voltage, same model number....

I would suppose there is  "military" TM for these Type 12 sets but I have
not found one yet.  Anyone?
