This is a very nice all original Spanish M43 Mauser Bayonet manufactured most likely in Germany for the Model 1943 Spanish Mauser. This bayonet is unmarked except for serial number on the cross guard. It is all original and correct. Mechanically this bayonet works great and locks onto a standard Mauser rifle as it should.
The blade is in very good condition throughout. There are some drag marks on the blade. It has not been sharpened or messed with.
The cross guard and pommel are both in very good shape. There is some light wear throughout.
The wood grips are in very good condition throughout. There are a few light handling marks as can be seen in the photos. There are two holes in the left grip.
The scabbard is in good condition throughout with some wear. There are a few dents in it as can be seen in the photos. It is the correct scabbard for this bayonet and is a refurbished German scabbard.
This bayonet would be correct for your SCW M43 Mauser. It will also work on any K-98 Mauser rifle.
