NRA Proofmark PDF
 

Saw this posted on the M1 Carbine forum, good proofmarking document - assume its accurate :burnout:

Thanks for sharing, with time I've realized that it's always useful to have a list of proofmarks handy, and somehow I always seem to find a new one that I'd never seen before.

Regards.

Not bad. But a bit dated.

Germany replaced the 'eagle' in their proofs with the text 'CIP'.
So 'Eagle/N' is now CIP/N, etc...
