This is one of the first bits I bought when I started buying 'art' glass, for the time that I had it it remained unidentified. A friend bought it from me when I was having a clear out a couple of years ago and a while later I spotted a few similar vases and thought it was likely made at Skrdlovice.
It now resides in deepest darkest West Wales (well it was today, it did not stop raining once) and today was the first time I have remembered to take a photo of it.
It's rather large at 32cm, very thick walled, extremely heavy with a heat finished rim.
