thanks Dave - very much appreciate your thoughts, and am tempted to agree with your suggestion that the colour of this glass might be described as 'honey'.
Believe I'm correct in say that the T/Webb product you have in mind is one of the three colours from the Gay Glass Range ........the other two being 'Spring' and 'Evergreen' - with 'Sunshine' (called Golden Amber by the factory) being the only one of the three to contain uranium.
Am attaching a pic showing the original glass together with a piece of T/Webb's 'Sunshine'. You can see some similarity, but there is a noticable difference in that the drinking glass is a deeper colour compared to the brighter amber of the Gay Glass 'Sunshine'.
In the U.K. we see a fair amount of Gay Glass 'Sunshine' - and am sure you're correct about the higher than usual uranium content.
However, I would say that 'Sunshine' is often noticable in the morning when the lemony green of the rims shows up (even without bright sunlight), so a torch not always necessary.
I'll settle for calling the drinking glass honey amber uranium glass, but feel sure the drinking glass has nothing to do with T/Webb's Gay Glass 'Sunshine', despite the very similar daylight reaction when the u.v. torch is applied to both - indicating, possibly, a similar uranium content. Of course, we'll never know what other constituents may have gone into the batch re the drinking glass.
