The local gunshop has a 29-4, 8 3/8" barrel with rib cuts for scope rings. Original box, tools and rings are included. First 3 of serial are BCC. Barely a turn line on the cylinder and no bluing wear. I think it was made between 1988 and 1991. Could anyone nail down the year of production for me and give me an idea of the actual value? The asking price is $685.
