Back to Poole Pottery. This was an eBay find earlier this month. It was painted by Pamela Bevens in about 1970. These Bowl came in at least 2 sizes. Number 38 is the smaller one and is 12cm in diameter. This Bowl is 17cm in diameter, but has no shape number printed. I'd be grateful to hear from anyone who know what the shape number.
I've Answered my own question. This is shape number 39 and there is one larger 11" diameter bowl number 40.
