This Colt Thunderer Model 1877 DA revolver was manufactured in 1897. The revolver has a 4 1/2 inch barrel and the distinctive checkered, hard rubber, birdhead grips. The barrel, cylinder, trigger guard and backstrap have a high polish blue finish. The frame and loading gate are case-hardened. The trigger and top of the hammer are niter blue and the sides of the hammer are bright. The black, hard rubber grips, are finely checkered and have the Rampant Colt trademark in an oval in the upper corners. The top of the barrel is marked "COLT'S PT. F.A. MFG. Co/HARTFORD. CT. U.S.A." in two lines. The left side of the barrel is marked "COLT. D.A. 41". The left side of the frame is stamped with the 1871, "73 and "75 patent dates in a three-line format followed by the encircled Rampant Colt trademark. The serial number is located on the front of the frame, the trigger guard, and the backstrap. The partial serial number, "374" is stamped on the rear face of the cylinder.

Excellent plus. The revolver retains 97% plus of the original blue and casehardened finish. The barrel shows minimal wear and retains the feathered polishing marks on either side of the front sight blade. The blue on the barrel, ejector shroud, cylinder trigger guard and backstrap is nearly all intact and finish loss is limited to traces of edge wear on high points and an extremely minor patch of surface rust on front grip strap. The color casehardened finish on receiver and loading gate is has vivid case colors. The fiery, niter blue, finish on the trigger, screws and top of the hammer is 98% intact. Markings are sharp. The grips are also excellent with minor high spot wear. Mechanically excellent. An outstanding example of a Model 1877 Thunderer DA Revolver.
