Need photos of the whole gun . The recoil lug and front screw position looks ala Mod 70 Winchester .
From the marks on the barrel I would say it has been removed and replaced by an amature.
My bad, it is a win model 70 pre 64, the ID was for the barrel. It looks alot like a hart barrel but I am trying to determine if it is true. It appears to be an older barrel, Seems trued to the action and doesn't look botched IMO
