I bought two from Kiesler's for $169 each. They're new manufacture, marked Series 70 in big letter rollmark and Colt Competition on the right. They're pretty clean for Colt, though mine is not fitting up real great with my Kart match barrel. If you are inflicting the gunsmithing on someone else, that's fine. The slides come without Series 80 holes, and have traditional Colt sight cuts and high ejection port.
