Thanks so much for showing the catalogue. At last an ID for the "Pear Bowl"! I never thought of it as possibly being Sowerby, the attention to detail on the fruit seemed to make it unlikely, being of a far higher quality than their usual standard that I've seen.
And as a bonus it seems I have a biscuit barrel in non-Uranium frosted green, sadly without its lid. (The one about half-way through with a geometric "diamond" pattern.)
As there are also examples of bowls without lids but with silver rims instead, were they ever part of a set of some kind? If not for a dressing table perhaps for the dining table?
