I notice that 'blue' uranium hasn't appeared on the Board's T/Webb colours/shapes archive - it's either excessively rare or it's not T/Webb.
Unfortunately, the Glassy Eye.com site doesn't provide any provenance for the 'stretched coin attribution, so we're no wiser there, and I think the nearest that the factory patterns get to this one is honeycomb, but am fairly certain this tumbler is not honeycomb, which is a smaller repeat pattern of a honeycomb.
If you look at the Board's search facility, it's obvious that some T/Webb surface patterns such as Water Wave, Ribbonette, Conifer etc., have caused confusion in the past - they appear nebulous and lack outline distinction - but coming back to 'British Glass' page 433, CH appears not to have included something quite like this one.
T/Webb did produce a range of tumbler colours/surface patterns in the 1930/40 period - some of which we have on the Board - the shape is common to all (at least it is for the series I have in mind) - and I've seen them at boot fairs many times. About equal numbers appear to be either marked or unmarked, and they occur in yellow uranium and non-uranium brown and of course clear, although can't recall green uranium but that may well exist and I've just not seen one. Their standard height is c. 100 mm (4 inches), and they all have the distinctive feature of a flared rim, and generally a large well-polished pontil depression.
We need someone to provide some more information on the Glassy Eye.com suggestion, please.
