I have a 1918 vintage 1903 in really nice shape except some idiot shaved the bolt handle to clear a scope years ago. Don't know a lot about Springfields but I am thinking bolts were not serialized to the action? If not is a new bolt body from that period from SA a tough item to find? Another strike against me is I live in Canada where 1903 parts are a little harder to find . Any info would be appreciated.
