The Diamondback is a Colt D-frame double-action/single-action revolver chambered in .22 LR with a 6-round cylinder. This example is built on carbon steel with a bright nickel finish across the frame and cylinder, paired with checkered walnut grips featuring gold Colt medallions. The Colt prancing-pony logo is present on the frame.
Its 6-inch carbon-steel barrel incorporates a ventilated top rib with rectangular ports and a full-length underlug with an ejector-rod shroud. Sighting is set up with a ramped front and a fully adjustable rear, providing a precise, user-tunable sight picture.
Visual details include the left barrel rollmark "DIAMONDBACK .22 LONG RIFLE." The revolver reflects the Python-inspired styling that defines the Diamondback line, notably the ventilated rib and underlug that give it a distinctive Colt profile.
Factory documentation is supported by the original woodgrain Colt box with an end label that matches the revolver. The "N" finish code on the label confirms the factory bright nickel finish, and the label lists the 6-inch .22 LR configuration.
