Single bead sight on the bayonet lug, with a six-hole heat shield over the barrel, cylinder choke, and a 2 3/4 inch chamber. "U.S." above a flaming bomb stamped on the right of the receiver ahead of the chamber. Fitted with an 18-groove forearm and a smooth pistol grip stock with a checkered Winchester buttplate. Includes a period leather sling and a Winchester M1917 bayonet with green leather scabbard. Length of pull 13 1/2 inches. Provenance: The George Moller Collection; Private Collection
