I agree with Wotan a later type Alcoso pommel. The rear center screw is a correct period configuration for an Eickhorn Heer scabbard but I do not see a picture of the screw they did use a larger type screw.
Due to the larger pics I did a closer look at the dagger. Against the overall very consistent patination I am not sure about at least the pommel (also the ferrule), for me it does look like an ALCOSO pommel with itīs pointed leaves.
I hope the army dagger aficionados jump in and tell us their opinion about this certain dagger.
