Condition: This pistol is in good condition, and we estimate that it was built around 1975, based on the serial number. The bore is sharp, with good visible rifling. The finish on the slide is blued, all original finish. At the muzzle, you can see in the pictures that the finish on the slide has a heat mark from firing the gun. It's about the first inch of the slide at the muzzle end. This is a hard gun to find with the matching serialized box and papers!
