hello Mark. The Davidson Victory mug is attractive, and same pattern was used for the Fesival of Britain I believe. I agree with you re the problems of keeping all the glass you find, but you do seem to be buying at good prices.
The uranium example I don't recognize - doesn't appear in the Stewart's book (although it does have the cut-out on the handle), and there's nothing in either of Barry Skelcher's books.
Perhpas Lustrousstone might know more.
Any Jacobean with labels is always worth buying - as it may well help with history of who made what, when and where.
Best of luck with your buying
