Okay I have inherited an M1 carbine from my grandfather and he said it was just a mail-order junker. So I thought okay It is still a neat gun even if it was a post-war production and it was a gift so no real loss. But then I showed it to my gun man so I could get a barrel band for it and he told me it wasn't a post war production because it had a bayonet lug,. Now I am super confused about it and want to figure out who made this dang thing. any tips?
