A blued bayonet with wooden grips and its original scabbard. The bayonet has a blued, contoured bird’s head pommel with a stud guide. Its black walnut grips, are fixed by a single screw. The blued cross guard has a circular muzzle ring to its upper projection, and a spring-loaded locking button alongside its lower projection. The 40.5cm blued blade has stamped to the ricasso ""S" and "A" (the manufacturer’s initials) above the image of a flaming bomb, underneath of which is a "1918" date, while the opposite side has "U.S" and a serial number of 1038474. The pressure-formed, cloth-reinforced, plastic scabbard has a slightly wider metal throat crimped to it, and tapers at its tip, where there is a hole for a tie string. To the obverse of the throat is stamped "US" within the body of a flaming bomb. Its mouthpiece extends backwards and wraps around a metal wire belt hook. Short, hooked posts are to either side of the mouthpiece opening, which pass through the perforations to the cross guard, that to the left engaging the aforementioned locking button.
