I bought five of these on ebay recently. Looks like a small wine glass , the height is 14.5cm and diameter at top of bowl is 6.5 cm. Has an attached bowl and foot to a barley twist stem. Glass glows bright green under UV light and has a polished pontil lens under the foot. The engraving of the crest with a lion sat inside a crown is really superb. The seller didn't know the family the crest belongs to. Does anyone know who may have made these ? Cheers, Mike.
