The description says “arsenal parkerized finish, wood very lightly arsenal sanded at some point, parkerized butt plate, stock is a replacement field stock with all correct markings but no sub inspectors and cut out for bolt was field altered”. If it went through an arsenal why is there no arsenal mark on the left butt stock and why are the 3 manufacturers cartouches on the stock? Those we’re only applied when the rifle was manufactured. I don’t see anyway that it is the original stock due to the lack of sub inspector marks. At the same time I don’t believe that stock was put on at an arsenal due to the lack of an arsenal mark on the left butt stock. If it was replaced in the field by an armorer then I don’t believe that there would be any marks on the stock. Most likely I think the stock is a field replacement or is a replacement stock somebody acquired and the manufacturer’s cartouches and proof mark were, as JGaynor has suggested, are probably fakes.
