This Sheriffs Model is quite unique ! as it was made outside the Colt Factory. Probably in the far southwest, Az. Ty. maybe even in Mexico. However, it was very professionally made, no doubt by a gunsmith of high quality and ability. Perhaps he had seen one or was familiar with the frame pattern. In looking at the forward frame configuration, it is identical to the Colt factory. It is a THREE inch barrel, but from close looking at the barrel it once had a Colt two line patent, originally 4-3/4 inches. the front sight is remarkable well done and in correct alignment. The Serial No. 10123X is present on all the correct locations although the butt it is faint and difficult to see. It appears all parts are the original Colt parts and all factory applied markings are clear and present. It is remarkable that ALL the working actions are correct: all hammer cock positions, safety, half cock, full cock. The cylinder rotates and aligns and locks tight for firing. Releases to fire , no problem. The current finish condition is one of reasonable wear. There is still blue on cylinder and barrel with a gray patina on the balance, an original patina no cleaning. The Colt has one piece Walnut grips, in a fine antique patina and fine fit.
