Included factory letter indicates a ship date of April 8, 1873 to M.W. Robinson, New York City, New York with 100 units of this configuration. The letter confirms this revolver's current configuration of 6 inch barrel, butt swivel, and smooth walnut grips. "55" marked on the left grip panel.

Good overall with a smooth dark patina, spotting/pitting, handling marks. Mechanically excellent.
