I have bought a lovely sugar? butter? or jam? dish. The dish is porcelain with cobalt blue, gold trims and orange flowers. It sits in a silver coloured basket and has a lid. No marks on basket or lid and they look newer than the dish does - perhaps made for it later?. The dish is marked underneath and after much searching on internet cannot find a similar mark. I know it has a registration diamond with I think IV at the top. Rest is unreadable. It has the number 2540 handwritten in orange. I woud really appreciate your help in identifying the maker or year it was made and even what it was really used for.
Regards
Sandra
