[ARC5] FT-243 Production Date?

[DSP3]

Reading the Green Books and IEE "Crystal Clear", it appears that the 
most prolific years of manufacture were 1943 and 1944.  1942 was a 
ramp-up with lots of orders.  The principle quantity units, from what I 
can glean, were for the BC-611, BC-659, and BC-620, and BC-1335.  These 
had large kits associated with them.  Now, other radios used the FT-243 
such as the BC-1306 , the pogo-stick, and a myraid of other units.  But, 
the FT-243 "spec" was the same.  The list of almost 100 companies is 
impressive.  The story of Leo Myerson's first big order is 
interesting... talk about pigeon to hawk, overnight.
