Certainly no concern from me, I would have expected a smaller maker to be purchasing parts from external suppliers and the one on your Hack was undoubtedly bought in.
Wittmann states that Herder also probably bought in their parts, although I have owned 2 by this maker with the leaf pattern shown above that I was unable to attribute to any other maker.
The upper facing acorns are a nice touch!.
