The right side has a tiny chip-loss at the bottom-front corner which has been smoothed out. There are no cracks. Overall, the grip is in Very Good condition as refinished Antique.

Type of Finish: Blue & Case Color

Finish Originality: The barrel appears to have had its finish intentionally removed. Otherwise, the finish appears Original

Bore Condition: The bore is light gray. The rifling is sharp where not interrupted by erosion. There is scattered light erosion and infrequent pitting in the bore.

Overall Condition: This revolver retains about 5% of its metal finish. There is a little bit of blue finish in protected areas such as the corners of the trigger guard, on the ejector housing next to the cylinder pin head, and on areas of the grip frame covered by the grip. The frame and hammer’s case color has mostly muted or gone to a light patina, with a little bit of color visible in protected areas. The barrel appears to have had its finish intentionally removed at some time in the past. There is some scattered light surface oxidation and minor erosion. There is a patch of chemical erosion on the outside of the cylinder between two flutes and behind one of them. There are some scattered light nicks, scuffs and scratches with tool marks around some screw heads. The action shows operational wear including turn wear on the cylinder. The screw heads range from sharp to tool marked with strong slots. The markings are clear. Overall, this revolver is in Very Good condition as Antique.

Mechanics: The action functions correctly. The trigger is crisp. The cylinder locks with little play on each chamber. The cylinder bushing is removable. We have not fired this handgun. As with all used firearms, a thorough cleaning may be necessary to meet your maintenance standards.

Box, Paperwork & Accessories: None.

Our Assessment: Colt’s Single Action Army is, perhaps more than any other, an iconic American pistol. It was the U.S. issue sidearm for the last two decades of the 19th century, used by pioneers, outlaws and lawmen across the expanding nation, and captivated audiences on the silver screen and television (and still does, today). This example retains strong mechanics, a nice bore for a revolver that would have seen use with black powder more than 130 years ago, and has matching serialized parts, though whatever was written in the grip’s backstrap inlet has been lost to time.

This revolver’s “U.S.” marking is not genuine, having been applied to give the revolver the appearance of a Model 1873 Cavalry revolver, but it was originally a commercial Single Action Army. It is rather interesting, though, as the barrel address is marked backward, with the lettering running toward the muzzle rather than toward the frame. The barrel address style is similar to that used on the Richards-Mason conversions, with wedge-shaped periods instead of square dots. The backward barrel address on this revolver matches up with a photo in the Kopec & Fenn book “Cavalry & Artillery Revolvers” of a revolver close in serial number to this one showing this Richards-Mason style marking, right down to the short serif on the base of the “P” in “PT.” as well as the missing period at the end of “U.S.A”.

Any of the 1st Generation Single Action Army revolvers are collectible, and this example’s rare barrel address marking may help collectors overlook the spurious U.S. markings. An opportunity like this doesn’t come by every day, so please see our photos and good luck!
