I think we are running into potential confusion

- I didn't think that I had implied there were two marks showing as plural - it was just the pickle showing the 's' - which, as an apparent plural, is unlike all the other back stamps from this output. At work now so I can't verify, but from my rather poor memory, all the books show marks that are upright scripts, whereas the pickle (in more ways than one

, and my piece from the other day, show scripts that are more italicised. Anyway, you have both dispelled my hopes that the suggested 'tureen' base was back stamped in 1908

Feel it is a fair guesstimate to say that both of 'my' marks are prior to 1926, since neither are shown in any books that I have seen. However, I now know that cut pieces, just like the pressed ones, can have many decades in production, so thanks to both of you for that. I guess that if I do have a tureen base, then I must now go looking for its lid.
