[Boatanchors] Lon ga Tone Automatic keyer

[WA5CAB at cs.com]

Bill,

I knew that I had seen the name "Lon-Ga-Tone" somewhere but couldn't remember 
where.  TM on the TG-1-(*) is TM 11-447.  I have a couple of extras of the 
1943 edition, as well as a BD-57-A (maybe 2).  But I think that's the only 
hardware I've ever had for the set.

BTW, the CW key used with this and some other code training sets was the J-38 
or another un-nomenclatured one, not the J-48.  J-48 is the scarce one with 
snap-slide base and aluminum cover used with the BC-654 in SCR-284.  J-38 has a 
fairly wide bakelite base and the key mechanism (which is not the standard 
J-37 used on so many other keys) has a lever switch that shorts the contacts to 
lock the circuit closed.  The other key has a narrower base that is indented 
to provide a space for winding up its cord.
