This is a very fine example of a Colt Model 1877 sheriffs Double Action revolvers that was manufactured in 1888. As noted this revolver itself has the desirable 3 1/2 inch, ejector less barrel with the "acid etched" barrel panel caliber markings on the left side with the top marked with the slightly larger Colt factory two-line address. The left side of the frame has the three-line/three-patent dates, with no Colt logo. It has an all blued finish with a color casehardened frame. It has a nickel plated finish with niter blue small parts. It has the small round blade front and frame groove rear sight. The frame, trigger guard and back strap have matching serial numbers and the cylinder is unnumbered. The loading gate is marked with a partial assembly number "202". Accompanied by a survey sheet from Don Wilkerson listing the features and markings of the revolver.
