There were Czechoslovakian vz58 Bayonet scabbards made for NBC (Nuclear, Biological & Chemical) applications, these are made of a green rubber material
German Bayonet Spare Parts have been available for armorers and through ebay and online store & traders for some years
Here are some examples of German Bayonet Spare Parts
Most of the Czechoslovakian vz58 Bayonet have a double rivet on the handle
Two types of pommel, one is longer
Some have a single Rivet on the handle
Is this a variant?
