I picked one of these up advertised as Stourbridge glass, then found another at a car boot, if you google it then you will find a couple advertised as Stourbridge glass, however, i have to agree with keith i have seen far to many since to believe it to be Stourbridge and own two, so if Keith has two and i have two and you own one how many more were made, I'm thinking China 60's mass produced when i look at mine. still any hand blown glass in my eyes is beautiful. I might be completely off track by the way. regards Chris.
