A friend(?) of mine had a Winchester proof stamp. Any vent rib gun could be turned into factory with a touch of the hammer

I also read somewhere that most of what we’re called factory vent ribs were Simmons BUT the ones that were considered factory DID NOT have Simmons stamped on the side of the rib .

maybe - but there would be two proofs unless they went to the trouble of removing the rib, striking the barrel to remove the original mark and then rebluing

a lot of work
