thanks to both - I get the impression that as David didn't record this slightly smaller size, then maybe it's a tad rarer (and I'm a big fan of rare things). In pursuit of the act of thinning out in order to make room for those things for which I feel more affection, I stopped collecting Chance some year or more ago, and now have only a couple of Yasmin plates plus this bowl.
I suppose always worth keeping the eye in on these sort of pieces just in case one day I come across a Baxter designed flashed ruby one that Chance did, which must be worth more, surely.
