One thing you must consider is that the stock may not have been on that rifle at time of rebuild, but it seems to be right to me. From what I have read by Bruce Canfield "It may not be JUST a REBUILD" in an early GCA Journal, is that soon after Col. James L. Guion became the C.O. of Springfield Armory (July 1950), the practice of stamping rebuilt rifles with the C.O.'s cartouche was resumed and SA continued production of replacement barrels into 1950 and 51 for use in the rebuild program. Your stock and 1947 SA barrel seem to fit. Hopefully others with more knowledge can give there opinions. To me it's a real nice honest rifle.
