[Collins] 312B-2

[Dr. Gerald N. Johnson]

Some KWM-1 flew in U-2 spy planes with the crystal plug in option. I 
remember seeing one in the cockpit I think at the SAC museum in Nebraska 
several years ago.

I think the KWM-1 production was all before Art's decree for random 
serial numbers so the highest serial number found may hint at the number 
produced. I know for sure that the random serial numbers applied to 
KWM-2 and S line.

73, Jerry, K0CQ, Technical Adviser to the Collins Radio Association.
