Anik, I think rather not; it was sitting among about 15 other Beranek / Skrdlovice pieces, latest pattern number around 1992, most from the 1970s and 80s, even a Svobodova "Galaxy" vase; no other Czech glass. The owner said he had it for more than 20 years, and that he imported glass from Beranek then. -- I guess this would possibly predate Svoboda's own glasswork?
Robert didn't object to the idea it was Skrdlovice production either...
(But I guess I will never know for sure)
BTW, even in the pattern book this one is referred to as "Vaza-Plastika"
It is really more a sculpture than a vase...
