sold to me as probably Webb, although I haven't yet found a matching picture. But there is a service by Walsh - albeit in Sunbeam amber iridescent, which this is NOT - shown in Hajdamach 20th Century Glass (page 125) which is otherwise a good match for both colour and shape with this goblet. I believe Walsh did do ordinary amber, so now not sure. Height is about 7.75" - 195mm .
Unfortunately, this piece doesn't have a ground/polished pontil depression which I would have though it might - doesn't ring when flicked, and has what appears to be acres of manganese glow. Has a moulded honeycomb pattern that I believe Thomas Webb did produce. Anyone think it might be either Webb or Walsh, and thanks for looking.
