Just found this post. It certainly looks like Sowerby 2652, although the colour is a bit dark - might have been made post-1957. 2652 was a small range made post-war to try to overcome the acute shortage of skilled mould makers. The simple rings (not very inspiring!) meant that most of the work could be done by the simple machines (lathes, milling machines etc) which were all that Sowerby had. This rose bowl, a fruit set and a three footed cake plate are all that I can remember. We introduced a yellow/"citron" colour specifically for 2652. Market not greatly impressed.
