Bishop & Stonier (Staffordshire)

It's confusing isn't it. This is why I originally thought it was Beswick & Sons. Slightly different pattern but still called Warwick.

Yes Beswick & Sons also used B & S. there may even be others!
Stylistically though, I would put this before WWI, which would rule out
Beswick & sons.

Brown and Steventon are recorded as producing Earthenwares, not china,
so that rules them out.

Back to Bishop & Stonier I think.

I bow to your superior power of deduction good Sir. Thank you.

Hi. I am trying to identify a dinner service that needs to be sold because of a house move. It belongs to a family member. I'll attach a picture of the symbol on the back too and hopefully it will mean something to someone here. I have trawled the internet but I havent found anything like it.
