Hi Ross, thanks for your answer. Of course, to little information from my side.
Two more pictures attached, bottom (no marks, etchings, etc.) and rim. Clear
to see the oval, lens-shaped diameter, no triangle. Two small, wing like stripes
on the sides.
Thought you guys here are so much into the glass theme, it's just a quick overall
peek for you to, to instantly identify manufacture, model and maker!
Best Martin
