Yep, Looks like the real deal. I bought a Sporter out of a pawn shop that was in a thumbhole stock nowhere as nice as yours. Unfortunately the barrel had been bobbed about 3/8" and the front sight set back. As already mentioned stocks and fittings are pretty hard to come by. I happened onto a M22 stock and mounted the Sporter action in it.Dressed up the crown put a Lyman globe front sight on it and made it into a "old school" high power rifle. It will clean the SR21 target pretty handily and I have shot 10 shot groups just over 1" with it. The load is essentially a hopped up cast bullet load with jacketed match bullets. My 9 and 10 year old grandsons can shoot it confortably without excessive recoil.
