1911Tex, I have an original .451 Enfield sharp shooter's rifle by Thomas Turner. It has the same checkering pattern at wrist and forearm, fully adjustable rear sight, rifle is marked "South Carolina"
on top of breech. Barrel is marked "Turner's patent" in ref to the rifling. The rifle shows age and use but bore is pristine brite. It has an egraved lock plate and breech.
I have several other civil war sharp shooter's rifle, one belgian .48 cal sold to the state of ohio. It also has a mint bore which leads me to believe the bore aspect on these rifles was well taken care of...Carl
