I have a 1st ('60),1 second gen ('62), and a 3rd gen Colt ('73). This happened over a period of probably 25 years. Could be a possibility of getting one of the 2nd gen. Colts I sold several years ago back again. Oh, and a 1st Gen. Mexican copy of a '73 that I got several years ago as a parts gun; been puttering with that off and on when the mood strikes.
