Thanks a lot for your comment, Robert!
Diameter is a little over 9 cm, height 21.6 cm. I hope that is within tolerance for Skrdlovice.
What persuaded me was the base -- sides slightly curved towards the bottom, then the bevelled edge. Identical to all my Skrdlovice pieces from the 1970s...
But ID from the drawing in a pattern book is surely not the most reliable thing...
I just could not imagine where a piece like this could have been made apart from Czechoslovakia.

And yes -- not the most typical or sophisticated Srkldovice design from that period -- but still a beautiful, quality piece (I am rather glad that the vase comes without the ring-shaped handles

And on the rare side I guess; or is it just that no one recognizes the pattern?
