Hello Blondin, in general the pics are few and not detailed for me to judge all parts of this dagger (what is the golden hue on the eagle�s left wing? Is it only in the photos?) but at least the trademark seems to be NO legit mark used during 33-45. It obviously should resemble the late EICKHORN trademark but has (big) differences.
Regards,
