[ARC5] [Milsurplus] Keys, mikes,and headsets question

[WA5CAB at cs.com]

The only application information I have ever come across on the J-38 is 
that it was used in various code training sets, not operationally.  The J-37 
could be used by itself if you fastened it down to a table or bench.  From 
what Mike just wrote that's probably what was done in aircraft.  Otherwise, it 
was the basic key in J-40,  J-43, J-44, J-45, J-47 and J-48.  J-41 is 
similar to J-37 but has additional contact and contact diameters are larger than 
on J-37. Used in TG-5 and sometimes issued with radio sets using BC-191 or 
375.  J-40 and J-45 are same except cord & plug.
