Model 1918 Bayonet, manufactured by Elsener Schwyz. Includes scabbard and leather frog.
Blade has a very slight bend that is barely noticeable. Walnut grip panels are poorly fitted. Pommel has heavy impact marks as well as some grind marks for some sort of modification. Scabbard has light finish wear and small spots of heavy pitting.
These bayonets were issued with the K11 and K31 Carbines.
The serial number indicates that this bayonet would have been issued with a K31 Carbine produced in 1945.
