Hey, great looking job, The Keystone stocks were somewhat thicker than S.A. or R.A. and that looks very close to the keystone, still a tad wider in some areas. I did notice the stock lugs are in the wrong direction, thats a nice detail to keep it an honest reproduction. Any and I mean ANY high end collector can tell a re-pro, if they can't they are playing in the wrong ball field. There are very pronounced production sequences that must be there, if not its a rep. If I were in the market for a shooter, I would do exactly as you've done, by the way the original stamp is a vee bottom, hmm-SDH
