Hi David

I'd already looked in Glen and Stephen's Vol.2 which shows the elephant bowls pat.2614 which have frosted sections, but the nearest to mine is a fruit set 2677, shown in Illustrated List 38 (1956). However, the horizontal bands are much wider and they are separated by four wide vertical panels, so I don't think it's Sowerby IMHO, but it wouldn't be the first time I've been wrong
