Rebuilt Winchester M-1 Barrel markings

    You will need to remove the upper handguard & see what markings are on top of the barrel. Are there any proof or punch marks on the right side of the barrel?

    I suspect the markings are commercial; USGI arsenal rebuild markings were never applied to the barrel, only to the receiver.

    Usual winchester proof mark and punch mark on right side of barrel. I was emailed and was told the O.B.S.3 stands for Ordinance Base Shop 3. These were field repair shops. Italy and Hawaii had these shops
