[Milsurplus] " M-1 " on BC-453 ?

[Robert Downs]

Moisture and Fungus Proofing was indicated by an MFP stamp, with date.  This was standard on all Signal Corps equipment by about mid-1944.

And Mike is correct that the M1 modification was the addition of a 1 MEG half watt resistor across the antenna post to ground on most receivers.
