This is some comment/guess about this infamous picture of a soldier, known as "Kampfgruppe Hansen".I have here the picture, and the question is if the knife this guy carries is adentifiable.
I pick some guesses about this knife, might be something I found as "german trench knife" with some variations.Have a look.
This is the closest one IMO(repro)
Another one (repro)
First from the left.
I know this picture is well known so maybe you already discussed that and know exactly wich blade is this.Thanks
