Is this thread still going? It will outlive us all I think. But it's good that Mr Jazz has kicked it into life again as I now think I know what his oval dish is (the photos posted back in June). It looks like a match to the Percival Vickers "Grosvenor" tableware set, which can be seen in full in their 1881 pressed glass catalogue. They produced the oval bowl in sizes: 5,6,7,8,9,10,11 inches.
I mention the full set briefly here where I lump it with their Jersey set:

The other photos I am less sure about.
Jazz, could I have permission to put your photos from the Jersey & Grosvenor sets on my website (with attribution)? I have been looking for an example from these sets for a while.
