The only mark that in my opinion seems genuine is the "13"
I don’t know enough about German marks to decide for certain whether the mark of Habsburg is genuine or not, but looking closely there is something that strikes me as wrong.

The mark of the manufacturer is beaten once, and could be a S and A intertwined, but also an S and V intertwined; however, the shape is so special that anyone who had already seen it would remember.
My gut feeling is that they are fantasy marks, but any opinion will be welcome.
Kind regards
Amena
