Thanks for reposting the picture, Ivo. I don't recall seeing it before so am intrigued by it now. That matt green's a very unusual colour for a Sklo Union piece isn't it? In the 1986 Rudolfova Glassexport catalogue on the CD with Marcus' book there's an example given of pattern 13153 so it was still being made then, but with a stated height of 205mm (20.5cm) rather than the 22cm of yours. No clues as to what colours are given in that catalogue and presumably the other sizes were discontinued sometime prior to 1986. Fascinating though.
