Rusted metal remains of a Model 1860 Colt revolver. Found at the site of the Battle of Beecher's Island on the Arickaree Fork of the Republican River, just west of the Kansas-Colorado line. In September 1868 a band of Army scouts were pinned down at this location by members of the Cheyenne tribe until relieved nine days later. It is believed this gun belonged to one of the scouts.
