Hi Kevin, I think
the shape in Skrdlovice designs is not necessarily the distinguishing feature...
For instance, Vizner, Palecek, Svoboda, Zertova, etc. all designed those heavy zylindrical vases, but using different internal decoration.
But there are more knowledgeable people here who could set me straight
BTW, your vase can be seen on the Beranek glassworks website
