Type of Finish: Blue

Finish Originality: Original

Bore Condition: The bore is mostly bright and the rifling is sharp. There is no erosion in the bore, but there is some stubborn fouling. In this writer’s opinion, the bore rates 9 out of 10.

Overall Condition: This handgun retains about 95% of its metal finish. The finish is thinning at most edges, more notable at the muzzle and the front edges of the cylinder. There are a few scattered minor marks. The action shows operational wear including a turn-line on the cylinder. The screw heads range from sharp to lightly tool marked with strong slots. The markings are clear. Overall, this handgun rates in Very Good-plus condition.

Mechanics: The action functions correctly. The cylinder locks up with no play on each chamber with the trigger depressed. The double action trigger is smooth, the single action is crisp. We did not fire this handgun. As with all used firearms, a thorough cleaning may be necessary to meet your maintenance requirements.

Box, Paperwork & Accessories: This revolver comes with a two-piece faux-wood cardboard Colt box with model-matching label and a non-matching serial number written on the bottom of the tray.

Our Assessment: The Diamondback is essentially a shorter framed Python both in the cylinder and grip frame, sharing similar aesthetic dynamics and is no less striking in appearance and mechanics than its predecessor. This revolver retains about 95% of its finish with wear consistent with responsible use over the last 57 years. This will make for a good shooter or addition to a Colt collection. Those familiar with the Python line understand the accuracy these revolvers are capable of, this one should prove to be no different. With its early production, it should also be a pleasing find for the collectors. Please see our photos and good luck!
