[Milsurplus] TBX part two

[WA5CAB at cs.com]

TBX manuals are scarce.  I've only ever had ones on three models, TBX, TBX-5 
and TBX-8 (three different ones on the -8).  The TBX contract is NOs-81118 
dated 22 January 1941 with supplements dated 01 April 1942 and 01 June 1942.  
That's the TBX, first model in the series.  TBX-8 contract is NXsr-38500 dated 22 
April 1944.  So that's six more contracts between June '42 and April '44 
(TBX-1 through -6 - remember the Navy standard of incrementing the suffix number 
on each new contract - the two supplements to the TBX contract rate as 
anomalies).  TBX-7 is a limbo set.  Only mentioned one place that I know of (manual 
for CRF-20337 Vibrator Power Supply).  Incidentally, the final manual on the 
TBX-8, and the only one I've ever seen with a NAVSHIPS number, is dated 30 
October 1945.  Cleaning up the mess after the war, I guess.
