Hi Lynne and Pip,
Once the labels have gone there is no way of discerning the difference between King's Lynn and Wedgwood production (that I am aware of), since it was the same workforce producing the the items.
I am having to assume from both your descriptions that we are talking about pattern number RSW 11, which was made under both names and appears in consecutive King's Lynn and Wedgwood catalogues. See also Tobin Figs 5 & 6, and Appendix 1 page 87 - "Domed Paperweight RSW 11/1, etc....". Susan Tobin also refers to them as Galaxy paperweights in the captions to the figures.
