[ARC5] CW and Mic plugs

[WA5CAB--- via ARC5]

The Navy had two numbers either of which may be found on what otherwise 
look like PL-54, PL-55, etc.  One is a five-digit number which is the Navy Type 
Number.  The other is an NAF number usually found on stuff ordered by the 
brown shoes.

All of the WW-II and earlier numbers began changing around 1948 when the 
Army and Navy were going through a fit of converting everything over to the AN 
system.  So PL-55 became PJ-055B (there was no Red), PL-54 became PJ-054B, 
PL-354 became PJ-054R, etc.  Most of the rest of the renomenclatured plugs 
didn't have a suffix color letter.  The only difference between the old and 
the new was the number.  So they are all interchangable (unless you encounter 
a stitch nazi).  

H-16/U is a renomenclatured HS-23 and has a PJ-054B plug on about a 12" 
cord.  HS-16 had pin plugs.  Although the Navy had some sets through the War 
that still used pin plugs for audio, the only usage I know of for HS-16 was 
with code practice sets and maybe some Morale receivers.
