Pamela, thank you for the attribution! I'm so happy you were able to recognise the glassworks :kissy:. Really great news!
When was the 'Stolz' range produced by Streit? 1930s? Thank you again!
EDIT: I forgot to say that the vase stands slightly crooked, which I find quite interesting. When I handle the vase, I cannot see anything which would suggest lack of symmetry. But when I put it down (and it doesn't matter if it's on the floor, counter, shelf, desk, etc.) it leans. The vase has a proud place on my living room shelf, but I've had to turn it 'just right' so that it looks straight.

I'm very happy with this piece.
