"George Armstrong Custer’s 7th Cavalry Model. The Custer 7th Cavalry Model is a very accurate copy of the first U.S. Gov’t models of 1873. These early firearms are inspected for ordinance by civilian inspector Orville W. Ainsworth, shipped to Ft. Lincoln and used by troops of the 7th Cavalry under the command of Gen. George Armstrong Custer. Each authentic firearm is properly marked with “Ainsworth” inspection markings, OWA Cartouche, 2 line patent dates and U.S. on the frame. Stamped into the butt of the backstrap is the company and 7th Cavalry markings. Production of this model is limited to 2000 units each of the 5 companies (C,E,F,I,L) that will perish under Custer’s command at Little Big Horn."
