Gentlemen,

that's indeed a very interesting discussion.

Just one hint:
When Vic Diehl and I did our first book, I visited the Federal Archives in Germany and the archives at Muerwik. I tried hard, but I was never able to obtain any written proof about any parts coming from different companies and/or used by different makers. That does not mean it never happened, but to explain an item with generic parts is just a speculation.
Different to the mass produced WH and WL daggers after the mid 1930's the German Navies had an ongoing demand for daggers, so the companies involved knew what to produce.
For obvious reasons the 1919 and 1921 patterns are difficult to judge, but the 1929 pattern daggers (theres no such thing like a "first pattern", except maybe the daggers worn by the Prussian navy around 1820 :-) should follow some specific company criterias. If they do not, they may be perfectly legit, but its unfortunately always a matter of believing in things.

I am not referring to the dagger shown in the initial post, this is just a general remark.

Best;
Hermann
