It could be that the scabbard was properly painted green in early 30ies to the frog,that has a police evidence, the rivet head was probably removed by preparing of plating, chrome plating is not typical for NCO dress pieces, maybe it could be real, but i am little sceptical about it, it has very crude tool marks on blade, that are not typical for a OEWG production, certainly the normal finished piece was accepted for using,that means prior 1917. best regards,Andy
