I have what appears to be the mentioned sight in it's orginal box. The box is marked 48 WJS for Winchester bolt action rifles Models 54 and 70. The sight and mounting blockare both stamped with C44, which I believe are production stamps. The block is marked Lyman WJS. The sight is marked on the elvation side with the running deer in a circle. But no where can I find a 48 marked on it. According to Nick Stroebel's book-Old Gunsights & Rifle Scopes, some were not marked with a 48, just a production stamp. Is this a 48? Any information will be greatly appreciated! Thanks!
