Hi Anik,
your effort is amasing. Your vase looks like ZBS and hence use to be attributed Miloslav Klinger. To search pfor pattern numbers is not efficient until we will discover original ZBS patern books.
To map ZBS is quite difficult task, the factory had run until 2008 so many old designs had been reproduced in slight modification.
I have seen also ZBS designs (Janku's dolphins) in show room of AGS - Svoboda in Karlov. I had asked him and Mr. Svoboda has confirmed to me that he simply has produced patterns that market in Prague required without care about authors or patterns. This is valid for many "hutni sklo: - free hand formed glass in country. So it will cost us some effort to sort it correctly.
But I have two good news,
Show and pattern room from bancrupted ZBS was sold to known collegue - glass collector - so information are saved.
I start to place all scanned Glasrevues (the parts of journals relevant for glass - no pottery and politics) from 1956 to 1992 to my web.
Some individal pieces that are not there I simply have not found yet. It is in German language, the English version of Glass review I havd not available for the moment.
So go to the
www.webareal/ceskoslovenskesklo - LH top - Glasrevue and brows the magic world of Czechoslovakian glass.
Please do not take everzthing printed in CGR as a law, there are some mistakes there as well.
