Kilian,
That's a nice rare mark on a bayonet, I would say that's a new one for the list. I don't believe I've ever seen one before either. I've seen the mark on SA/NSKK daggers occasionally & Fisher's list shows Gebruder Krusius as an HJ knife manufacturer as well. The firm was in business from 1886 through 1983 when sadly, they went bankrupt & their machinery was sold off at auction.
Can you show the rest of the bayonet? Is this a Weimar era piece?
