Model 1918 Swiss bayonet manufactured by Elsener Schwyz, who would later become Victorinox. Includes steel scabbard and leather frog.
There is a large mark in the wood grip.
Model 1918 bayonets were issued with the 00/11 Carbine, K11 Carbine, and K31 Carbine. As the serial number 546043 is out of the serial number range for the 00/11 and K11 Carbines, this bayonet would have been issued with K31 serial number 546043 in 1935.
