I just bought what I believe to be an older hawken style rifle. It has around a 33 inch 1 1/8 diameter .45ish caliber barrel with what looks to be ROTURNE engraved on the barrel. The lock has the initials L.M. Engraved on it. The stock is a plain walnut half stock. I was wondering if anyone has ever heard of either maker and a rough time frame the rifle might be from? I apologize for the low quality pictures. I am traveling for work so the pictures were took in the cab of my truck.
