Helga, I am sure your vase is Czech, and Skrdlovice; I had a look through the pattern books, but I am not certain about the pattern Nr.
Designer could be Jan Broz or Jaroslav Beranek, early 1950s...
I think you may call it a bullet vase if you wish, but usually this term is used for Rudolf Schrötter's Sklo Union vases (pressed glass, not hotworked like yours)
Nice vase!
