Yes I've seen this article, but (at least for my vase)
the Catawiki-Link, is by far the best match I've found yet.

That one's supposed to be french.
Still, the schachtenbach/bohemian also matches a little.
In terms of glas, and gold enamel.
Could this really be 24 carat gold?
And where to find out? Juwelery store?
