Colt Single Action Army Cavalry Model, serial number 137596, made in 1891, in .45 Long Colt with the 7 1/2-inch barrel. The barrel blue is thinning but present; the frame keeps traces of case colors and has mostly turned to a gray patina. Both grip panels still show cartouches, with the right side mostly faded. The supplier describes it as a very fine, sharp example. A factory letter and two binders of research accompany the gun; the researcher concludes it was issued to Company K of the 8th Cavalry.

This Colt belongs with collectors of U.S. Cavalry Single Action Armies. The visible cartouches, the thinning original blue and the gray frame are the condition facts, but the two binders of research and the factory letter are what set it apart: they give the next owner a documented trail to Company K, 8th Cavalry, to study and extend. It is a display and research piece, not a revolver to shoot; the 8th Cavalry attribution is the author's conclusion.
