This revolver and others like it with "US" markings on the trigger guards and mixed numbers are believed to be Civil War contract Model 1860 Army revolvers that were refurbished by the government for use by the U.S. Army, especially the cavalry, out West during the Sioux Wars, Yavapai Wars, Texas-Indian Wars, and other conflicts before they were replaced by converted Model 1860 Army, Single Action Army, and Schofield revolvers. They are believed to have been in part issued to the famous "Buffalo Soldiers." Some were likely used to arm Indian scouts and other Native American allies as well out West. The added "US" markings on the trigger guards may have been added since the "US" markings on the frames are sometimes worn away and as a clear way to distinguish privately purchased arms from government property, especially since former government owned weaponry was also being sold as surplus. It has the usual markings and features of a U.S. contract Model 1860 Army aside from the added marking and mixed numbers. This example has the three-screw frame and back strap that are cut for use with a shoulder stock (not included). The frame serial number dates to 1863.

Fine with 40% arsenal refurbished blue and 60% case colors remaining, aged patina on the brass, gray and brown patina on the balance, some minor oxidation, and general minor wear. The grip is very good and has moderate scrapes and dings, a small chip at the toe, and traces of the original cartouches. Mechanically fine. This would be a great addition for any collector of antique Colts, Indian Wars items, or U.S. military firearms.
