Ron, you are right in that "textbook" is always easlier to sell. However, there is variants and they should not be considered fakes. Johnson also pictures one by Paul Weyersberg, with Eickhorn fittings and the flaw.
The one I refered to in Wittmanns catalogue was unmaker market and it sold. It also had an inscription on the blade. Graig Gottlieb also sold one not long time ago. Hopefully we someday will know more about these rare and beautyful daggers. I like mine and would'nt change it. Hope also to find an Horster that I can add to my collection.
