Stock Configuration & Condition: The grips are checkered black hard rubber on a bird’s head grip frame, with a Rampant Colt in an oval at the top of grips. The checkering shows light to moderate wear that is worn smooth on the bottom shoulders of the grips. There is a tiny mark in the upper edge of the circle around the Rampant Colt in the right grip and a mar in the checkering just below the logo. There are no mars in the checkering of the left grip. The detail in the logos is exceptional. The grips are in about Fine condition.

Type of Finish: The barrel, cylinder and grip frame are blued and the frame is case colored. The top and bottom surfaces of the hammer and the trigger are fire blued.

Finish Originality: The finish is original.

Bore Condition: The bore is bright with sharp rifling. There are a few spots of very light erosion from the muzzle back about 1”, mostly in the grooves.

Overall Condition: This revolver retains about 80% of its metal finish. There is finish loss from holster wear on the left side of the barrel at the muzzle, at the front of the ejector rod housing, on the front edges of the cylinder, and finish loss in the backstrap. There is thinning in the ejector rod housing, on the edges of the trigger guard, and on the cylinder. The frame is developing a light plum colored patina. There are scattered spots of erosion over the gun. There are also a few light handling marks scattered over the barrel and cylinder. The cylinder pin and hammer knurling show very light wear without mars. About half of the screw heads are slightly disfigured. The markings are clear. Overall, this revolver rates in about Fine condition.

Mechanics: The action functions correctly in both single and double action. The cylinder lockup is SOLID! The trigger pull is smooth in double action and breaks crisply in single action. We did not fire this revolver. As with all used firearms, a thorough cleaning may be necessary to meet your maintenance standards.

Box, Paperwork & Accessories: None

Our Assessment: This Thunderer is in about Fine (about excellent for an antique) condition with 80% of its original finish remaining. The bore is bright with sharp rifling and a few spots of very light erosion near the muzzle. The action works correctly in all respects, and the cylinder lockup is SOLID on all six chambers. We have seen new modern revolvers that were new in the box that didn’t have cylinder lockups this nice. We don’t see very many 1877’s with bores and actions this nice, and anyone interested better jump on this one while they have a chance.
