USGI WWII barrel proofs
A question came up recently with several opinions. When were the barrels of USGI rifles proof stamped: flaming bomb and date? Due to war time production my guess is that a random selection was made,fitted to a reciever and proof fired.The rest were inspected and stamped.Later (next week,next month?)to be fitted to a reciever.So I might have a 9-43 barrel date but an earlier or later reciever serial number. Is this all wet?
