This classic example of the "Yellowboy" dates to 1870 while many areas of the American West were actively contested. Winchester's new Model 1866 found ready customers in both the pioneers staking their claims on western land and the Native Americans fighting to hold their territory. Multiple Model 1866s are reported to have been used at the most famous Native American victory: the Battle of the Little Bighorn, and some have even pointed to the use of repeaters as a factor in enabling the Lakota, Northern Cheyenne, and Arapaho to overwhelm Lt. Colonel Custer's detachment of the 7th Cavalry who were armed with single shot trapdoor carbines.

Good with an overall "frontier issued" appearance suggesting many years of hard use including dark brown and gray patina on iron, aged patina on the brass with signs of prior cleaning, refinished wood with "TH/E" carved into the right side of the wrist and "AH" carved into the left side of the forearm, the underside of the forearm worn through to the magazine tube, some chips and cracks, and moderate overall wear. Mechanically functions.
