This is a very nice WWII era unmarked German K98 Bayonet. Mechanically this bayonet works as it should. The metal on the bayonet has been chromed at some point. There are no markings on the bayonet.
The scabbard is in good condition throughout. There are some dents and dings throughout.
This could have been used for ceremonial use, chromed after WWII by a GI as a trophy, or used during the Spanish Civil War. Either way, it’s a nice bayonet that would look great with your K98 Mauser.
