Very nice Colt Diamondback .38 special, believed made in 1975. Perfect operation and no wear marks. I would have asked a higher price except for one small issue. Beyond the usual cylinder ring there is a second ring approximately 1/4 “ forward. This mark lines up directly with the sideplate screw. Appearantly the previous owner had not tightened it properly and it protruded enough to make slight contact with the cylinder and mark it, before he corrected it.
