5-1/2″ bbl in 38 WCF. Good looking 1st gen Colt with nearly all case colors remaining. They are still quite vivid. Bbl blue at 90%+. Hard rubber grips are in very good condition with just a couple light scuff marks. Inside is just as pretty with a near excellent bore. Solid good sounding action. 350k serial range puts it towards the end of the 1st gen. Good looking Colt!
