I have just seen one for sale, exactly the same in amber glass . It carries the Crown Stamp GR with a crown, used from 1910-1930 and the area identification number 64, which is for Newcastle upon Tyne, the same one shown in the Jobling catalogue. This at least indicates it was made by one of the North-East factories, but I can't find anything similar by Sowerby or Davidson, the two major beer glass makers.
