very nice - looks to be an interesting purchase. Is it my eyes, or am I seeing the word WALSH toward the outer rim on the underside on one glass in picture three? If these are Walsh, then might the inclusions/bubbles indicate these glasses might be from the 'Pompeian' range do you think? Unfortunately, I don't see a 'waisted' shaped tumbler in Reynolds book, though certainly Walsh did produce tumblers in 'Pompeian' colourway. Looking at my several different coloured varieties of Webb's tumblers, the base finish on the examples here are very different to Webb's, so that might be another indication these have nothing to do with Webb.
Edited: ......... Having now looked in Hajdamach would add: ............. In a similar way to Thomas Webb, Walsh produced their own take on uranium yellowish glass, which apparently they called 'Sunbeam' amber - some of which was provided with an iridescent finish. I mention this as although the tumblers shown here have inclusions in a vaguely similar way to 'Pompeian', IMHO, and to my eyes, they look to fall short of the full blown appearance of 'Pompeian'.
