Manufactured in 1969, this early Colt Diamondback D5520 pairs the compact D frame with a 2.5 inch barrel, .38 Special chambering, adjustable sights, original blue finish, and checkered walnut Colt grips. Retaining approximately 96 percent of its original metal finish with an excellent bore and tight lockup, it is a handsome example of Colt’s classic Diamondback revolver.
