This model was manufactured circa 1873 to 1890 and featured a 3 1/2 inch round barrel with the Hartford address, 1871 and 1872 patent dates marked frame, no ejector, and no barrel lug plug as the barrels were specifically manufactured for this model and not altered from percussion model surplus. The cylinder has the stagecoach scene, and the conversion breech plate lacks a loading gate. Barrel wedge is numbered to a different gun. Matching serial numbers appear on the frame, barrel, trigger guard, back strap, and cylinder.
