I also think they look what I think of as German, so I'd be very interested to see if any of these style turn up with Scandinavian labels, that would be new info. Hope you can fish out the Nybro ones, Paul.
If they're German - not Wiesenthalhütte I think, their finishing is better (no lines or irregular tops). The style doesn't look quite Walther (then again, Walther made many different ones, so I can't really exclude it). But for the rest, from the irregular top and the sort of press mark lines it could be Marsberger, Ingrid Glass, Schott Zwiesel or a smaller company. We'll have to wait until one turns up with a label...
