sorry, but I really can't see the connection (as regards the pattern, I mean). I'm unsure whether the two separate Rd. Nos. refer to the shapes, or patterns - possibly the shapes I think. I'm usueless at finding my way around the GMB data sites - must try harder.

With regard to the boat flower trough, I do have the same size example, in clear, which appears to be from a crisp pressing - and I'd forgotten that this is the piece which carries the words GRACE.DARLING (why the stop I don't know, unless it's to indicate the fact there are two words).
The name is higher than the Rd. No. (as you can see in the pic.) - and the odd thing about these words/figures is that whilst they are all in relief on the inside of the boat - the name can only be read correctly from the outside, whilst the Rd. No. is seen properly only from the inside.
I'd give my eye teeth (if I had them) for this uranium example - but what surprised me was the shade of green - I was expecting to see a more oily yellow colour.
I might suggest though, that in view of the seller's comments about the feintness of the Rd. No. - and (obviously) the lack of the name, then do you think this green pressing was made many years later from a very worn mould?
However, thanks for taking the time and trouble to include the links.
