Although I'm fairly sure it's not - I've looked on the RSW on line collection and ebay but no bowls at the moment. The colour seems right and I know they did some bowls in a similar shape - also the slightly raised blip on the underside of the foot is o.k. and it rings very well when flicked. No backstamp unfortunately, and obviously no label, and no picturers of bowls in Susan Tobin's book. Height is 3.3/4" - 95mm. I'll take it as a no unless anyone is positive it is, and thanks for looking.
