Hugo Koller WW1 trench knife. Real or fake?

[beardrake]

This nice trench knife came in. I really would like some opinion here.
Do you think is real or repro?
I'm sorry but I have only these three photos.

It's marked Hugo Koller solingen.

superb original Keller!

I don't like the maker's mark if you compare to this original.

Thank you very much Ralph, I think the same.
Anyone have photos from specialized books?

How do you like this one? May be Keller had more then one wariant of his maker mark?

I think that yours is better than mine
Could you show me other photos?

That is not so. I have the same wariant of a Koller knife that you have. The last pics was from some other forum.

Here we have another mark... Wery similar but not the same. See the eagle tail.
