I've just bought this at a car boot sale and identified it as by the company STS( Sjedinjene Tvornice Stakla) Abel of Zagreb in the former Yugoslavia, now Croatia. I first identified it from a similar one on Pamela's pressglas-pavillon but it's not in the 1936 catalogue on glas-musterbuch. It's 28cm.x8cm. with a holly? motif and has lots of chips but, not surprisingly, it was very cheap.
