ZADMAT these are twoo good leads on correct stocks. As Mike points out either would work and they have the advantage of coming with the barrel guard, stock metal and sling. According to my data most of the original rifles in your s/n range would have come with the full pistol grip version ("C") of the Stock, M1903A1. For a hundred bucks I would grab the "C" stock on the buy it now if its do-able. Good stocks are few and far between.
