Model 1918 Swiss bayonet manufactured by Waffenfabrik Neuhausen. Includes steel scabbard and leather frog.
Patina on the pommel. A wood plug has been inserted into the bayonet's mortise slot, which is used to prevent the bayonet from being attached to a rifle. The wood plug is not permanent and can be removed by pressing on the press release.
Model 1918 bayonets were issued with the 00/11 Carbine, K11 Carbine, and K31 Carbine. As the serial number 900200 is out of the serial number range for the 00/11 and K11 Carbines, this bayonet would have been issued with K31 serial number 560021 in 1936.
