Mauser 1898 Bayonet
 

I just found this in a pawn shop and I'm told it was the first pattern Mauser 1898 bayonet. I think it's called the Imperial S 98 nA with the long narrow blade and leather scabbard. All metal including that on the scabbard is plated and no markings so I assume it's a "parade" bayonet and private purchase. Anybody know anything about these and have any idea of their collector value? This one is excellent condition.
