Hi,I found this piece on eBay and thought it was the right colour for whitefriars Powell glass,It's 23.5 cm in ht,very light with a nice brittle ring .The Pontil is central and it's mould blown with faint horizontal lines,which I couldn't see from the photo I saw before pushing the button,it was advertised as retro vintage but I wonder if it may nit be turn of the century?..any help very welcome thanks.
