Hey Eric,
thank you for your detailed answer and the time you spent with my Paperweight. I know it is quite difficult or nearly impossible to track down the specific maker...I also spent hours and hours with the research.
Normally I collect Murano Glass, Bohemian and also French Glass since 20 years (Vases, Ashtrays, Sculptures...) Also spent half of lifetime with research of Designers, Styles, auction catalogues and so on. I know there is so much inaccuracy on Etsy, Worthpoint and all over the internet.
There are big auction houses in Germany, like Quittenbaum in Munich, I bought auction catalogues with results of the auctions and so on. And I found a few mistakes attributing the items to Designers. They are not all experts, that's for sure.
Regarding my Paperweight it is clear, that it is made of high quality and nothing cheap. My first impression, as I saw the flower and the whole inside, this might be Bohemian. But I couldn't found any Czech Paperweight with a cut like this. Do you have any picture of one? I would be very pleased!

Caithness was not in my thought...wouldn't they have signed such a special, abstract Paperweight and give it a name?
And why are you certain, it could not be french/Saint Louis? There were times, they didn't sign their work...but for me, especially the glass speaks french language, it has such a clearness...
I hope my english is good enough, to understand, what I am trying to express!
Thank you for your time, I really appreciate it!
Greetings, Timo
