´Netzdekor´ would be the closest I could think of at the moment...
I really don´t want to sound discouraging, m, but I think the online options may lead
nowhere in this case. I´ve now and then tried to find info on Schliersee myself to e.g.
back up other ebay attributions - to no avail.
I´ve no experience about contacting Passau - hence my question.
