Any one have an idea what a Ruger Blackhawk 45 Colt pre transfer bar is worth? It shows a small amount of wear on the back sight, almost no ring around the cylinder no wear on the end of the barrel, the grips are original and in excellent condition. Manufacture date 1971. I believe these were only made for 3 years. Looking at the barrel, cylinder and overall I would say it has had less than a box of cartridges put through it. wM1
