The High Leader NSKK Dagger with damascus blade has been known to be in collections as long as I have been in this hobby (50 years). What has probably given rise to doubters was the introduction of a standard NSKK Dagger with the "supposed signature" of Huhnlein on the reverse of the standard blade as it was seen on the damascus pieces. As I remember, these appears in the early 1970s, usually on an RZM marked blade.
Another feature of the originals that led to some questioning was the crappy middle scabbard band-unique to the Huhnlein NSKK Honor, but that was the way they came.
