Receiver B3A
Jim,
I don't have B3A in my database yet but B2 shows up in May and June 1939, B3B and B3C in September 1939.
Just in case it might be B34 instead, this shows up in September and October 1944.

B3a
The heat lot number is definitely B3A. Also, the drawing number is D 28281; there is no revision number. Additionally, it has the square op rod cut and does not have the 7th round repair.
Thanks for the information. If it helps your data base I have receiver 102; its heat lot number is R1.
