Remington Chrome Moly barrels

[Dean Romig]

No Dave, just the MO and no other stamps referring to barrel steel or any of the other "meaning unknown" stamps. Suspecting the MO is an early designation for chrome molybdenum... certainly a distinct possibility.

You could be correct Dean, but I have my doubts. Chrome Moly steel alloys predate these guns by many years and the AISI designation of CrMo goes back to the teens.

Edgar-I don't disagree with your metallurgical point, the issue as Dean says is when did Remington start using THEIR CrMo barrels as opposed to whatever PB had in stock and was there a marking of same on the barrel flats.
