I just returned from Hungary, where I had the pleasure of spending some time with Janos and where we spent a super evening looking at daggers and more daggers.
You slant grip Heer guys out there would have been fascinated, I know I was. I managed to convince Janos that this Luft2 deserves a spot on the JohnZ wall along with its other TM variation brothers.
To answer the question as to whether this could be an army blade (Wusthof is known as a rare maker of Heers) in Luft2 fittings:
1) There is no more of a premium for a Wusthof Luft2 then there would be for a Wusthof Heer.
2) Heer collectors probably number more than Luft2 collectors so a Heer would sell mpore quickly and probably more expensively than an Luft2.
3) This item was sold to Janos as a Luft2... no special mention of the TM, and I bought it at the same price as I had paid for some of my more scarce items, like Kolping and Fridericus).
4) A lot of these cottage manufacturers purchased their fittings from other manufacturers and, since they alreay had the blade to make Heers, they could just as easily purchase Luft2 fttings from the same manufacturers.
Anyway, here are my pics of this dagger, now hanging on my wall.
