You'll have nicks and dents. Maybe a bit of wood chipped off somewhere. My latest one looks like it took a bayonet to the front handguard. Stock wasn't matched, but didn't look bad. If you get lucky, you'll get one of the thinner wristed ones, but most I have seen had the thicker wrist.
Bore should be good and shootable. All in all, a good gun, but nothing like a colectors grade condition. Something that a guy would be issued on the battlefield and be happy with. Good enough that my grandpa would rather have that one over the one he had in the Marines in the early 50's.
