good morning each - I've lapsed and no longer collect, but saw this across a crowded charity shop room and couldn't resist taking home, and occurs to me it might be of interest to others here. No longer have my books, so in the dark and hoping some kind soul will have a look in Hajdamach's book for C19 British Glass - the reason being that Thomas Webb is the only maker's name I can suggest - though of course this may not be British - and from memory recall that book lists and illustrates most of the TW moulded surface patterns, plus they were one of the vastly better known British makers who incorporated u. in the batch. Richardson, possibly, might be a contender??
Judging by wear and shape (plus u. content), I'm thinking this is a 1930/45 period piece - tumbler/bucket shapes were popular then - the wear is heavy - the u. is strong - the ground/polished pontil depression is high quality. The pattern is a variation on some form of very irregular honeycomb design - becomes stretched toward the top rim with the final couple of inches simply plain glass.
From memory, neither Stuart or W/Fs used u. in the C20, and TW created a large range of surface patterns which they used over a long period of time (many of them have been shown on the GMB) - perhaps this one has some similarities to Webb's Gay Glass range?? Certainly TW pieces are found commonly without their backstamp.
Even in poor daylight the u. content can be seen especially around the rim, so torch fortunately not needed in the shop. Height is c. 10 inches (25 cms.) - rim diameter c. 7 inches (18 cms.) I've looked till I'm blue in the face but unable to see any kind of backstamp etc.
Should this not be British, then I'm clueless as to origin or maker.
Thanks for looking.
