A barrel rib is marked "ALLEN & THURBER NORWICH C-T" (traces remain) followed by "PATENTED 1837 CAST STEEL" on the next rib. The left side of the bar hammer is marked "ALLEN'S PATENT" and the frame has the standard broad leaf hand engraving. Plain nipple shield and conventional trigger guard. Barrel, mainspring and frame serial numbers match with grips numbered to gun.

Good. Overall the metal surfaces exhibit a smooth gray patina and darkened minor pitting (mostly contained to the nipple shield and frame). The grips are good with some minor dings and scratches and a few minor gouges. The barrel cluster is slightly loose, but action functions. The markings are slightly faint, but legible.
