Overall Condition: This handgun retains about 94% of its metal finish. There is moderate thinning from holster wear along the left side of the barrel and the underlug. Holster wear is evident on the right side of the barrel as well. The barrel itself has a few light nicks. Minor thinning can be seen on some lower edges of the frame and guard. The cylinder has scattered minor nicks and infrequent spots of minor surface erosion. The screw heads are sharp. The markings are clear. Overall, this revolver rates in Fine condition.
Mechanics: The action functions correctly. The cylinder locks up solidly on each chamber with the trigger depressed. The double action trigger is smooth, the single action is light and crisp. We did not fire this revolver. As with all used firearms, thorough cleaning may be necessary to meet your maintenance requirements.
Box, Paperwork, and Accessories: This Diamondback includes a Colt zippered soft case, and a letter of provenance from Colt historian Beverly Jean Haynes.
Our Assessment: The Diamondback is effectively a shorter framed Python with a dash of the Detective Special, both in the cylinder and grip frame, sharing similar aesthetic dynamics and is no less striking in appearance than its predecessor. This revolver retains about 94% of its finish with some scattered wear that is most notable on the barrel. This will make for a great shooter or will do well to help fill out a collection of Serpent guns. Those familiar with the Python line understand the accuracy these revolvers are capable of; this one should prove to be no different. Good luck and happy bidding!
