Marked "PATENTED 1837, CAST STEEL" on one of the barrel ribs. None of the usual Allen marks appear on the pistol, indicating that it was made for one of Allen’s distributors. Features German silver escutcheon on each side of the smooth bag shaped grips and simple scrollwork on the frame.

Good. The metal surfaces exhibit a brown mottled patina with a smooth dark patina on the trigger guard and front grip strap. The escutcheons have been cleaned at one time and are now beginning to age again. The grips are very fine with some minor scratches and nicks. The markings are legible. The engraving is clear. Mechanically needs some work.

"ALLEN & THURBER WORCESTER" is marked on one of the flutes, "PATENTED 1837" on the next and " CAST-STEEL" on the next. "ALLEN'S PATENT" is marked on the left side of the hammer. Standard light broad leaf hand engraving on the frame and nipple shield with two piece smooth walnut grips.

Fair. The barrel exhibits a mixture of a smooth dark patina and a dark mottled patina. The rest of the metal surfaces exhibits a mottled gray patina. There is a large chip on the left grip near the frame, otherwise the grips are very good with some minor scratches and a few moderate dings and dents on the butt. The markings are very faint. The engraving is beginning to fade.
