then honeycomb it may well be Wolfie - I couldn't really see clearly from the first pix. and from experience I know these surface patterns from T/Webb can be confusing.
Wolfie hasn't commented that his piece is iridescent, so on that basis would assume his is not from the Walsh range showing in Hajdamach, although it may well be that Walsh made a straightforward amber uranium mix that wasn't given an iridescent finish. Does Christine know if that is the case?

Could be wrong, but the surface effect on the Walsh stemware showing in Hajdamach appears to be a sort lattice pattern.
The lack of ground pontil is quite in line with much of Walsh's smaller stemware - I've a rummer and wine glass from them that have a similar finish to the underside of this foot - although they did grind the bottoms of tumblers it seems.
Walsh were hit and miss with their backstamp, and even when present can be the devil to see. Difficult to judge the lengths of stemware or to make comparisons, from pictures only, but you may be correct that Walsh are longer.
Anyway, these are a nice find and to have a set of eight, well................we're all very green.
