I have some suggestions I would like to share.

1. Exclamation point does not look like Eickhorn one.

2. The shape of the ferrule, pommel and crossguard seems to be different from original Eickhorn.

3. Pommel should be screwed on the back not on both sides.

4. The grip wire looks too new.

That is what I can see. I would not buy such an expensive dagger if it is not a textbook example.
