Thanks to both of you.
I think I know what this is, and probably the designer, but as yet, I have no documentary evidence to back this up.
The reason for eliminating the Scandinavian connection, is that recently I discovered a "Praha" look-alike pattern from one of the Finnish companies. That being the case, I am trying to make sure this pattern was not from one of the Scandinavian pressed glass manufacturers.
Do these turn up in the Netherlands?
Thanks again and regards,
