Swiss Model 1918 Bayonet, manufactured by Elsener Schwyz. Includes scabbard and leather frog.
Light patina on the pommel.
Model 1918 bayonets were issued with the K11 and K31 Carbines.
The bayonet's crossguard lacks a serial number, either meaning it was never issued alongside a rifle, or the serialized crossguard had been replaced. Estimated to have been manufactured before 1951.
