Winchester P1913 dated 1917 bayonet with scabbard. Marked with the model year "1917" at the ricasso, along with the makers stamp "W" within a circle for Winchester.
The other side showing the 'flaming bomb' ordinance markings, and an eagle's head acceptance stamp. It is also marked US, and carries an X to denote that it has been bend tested.
In poor condition. The scabbards leather is fairly worn and fragile and the bayonet is missing it's attachment bolt.
