with this 'rose' colour, thought there was a very good chance of this being Wedgwood, and colour is marvered into the outside over clear glass. Nicely ground/polished pontil, and stands about 4.25"/110mm tall. Have looked all over, but unable to see any acid backstamp. Holds about 14 fluid ounces (approaching 3/4 of a pint) - about 0.4 of a litre. I've looked thru Susan Tobins book, but don't think there are pics of a similar tankard, and although there are several mentioned in the index, I'm not sure which one this might be. Would be grateful if someone is able to let me know which reference No. this refers to, and thanks for looking.
