I can't vouch for the people that came up with the logo; but it is a sticker for a Machine dealer in the town of Villach, Austria. They sell new and used woodworking equipment. The owner is Siegfried Schack...so SS is his initials, must be a family thing, another Schack that works there is Stephan Schack. The SS Sigel is actually different, these shown have a serif on them and rounded corners. But yeah, first look, it appears close, probably an unfortunate coincidence, but then?
