Got an 80 or 81 model Security Six. With box, papers, and original grips. 2 3/4" barrel, blued. Very slight ring on the cylinder and a small handling mark on the blackstrap between the grip panels. Other than that its in very good condition. When I took ownership of it, it had never been fired. Since its been shot around a hundred times. Had I known what I had I would not have shot it. Any ideas to its value?
