I bought this piece from a glass collector at a boot sale but didn't ask where it was it from. From the 'birdbath' base and the design I thought it might be Sklo Union. I looked on Google and eBay and can't see anything similar, so cannot confirm it. Is it Sklo Union? It's 185mm height x 62mm wide. No pressing marks, base corners are ever so slightly worn suggesting some age but otherwise perfect. No makers mark. Many thanks.
