I have so much blue to sell - this is in perfect condition and still retains its shine. By famous potteries James Kent Ltd - says MADE IN ENGLAND so after 1921 - I'd say 1930/40s. The inside is also perfect with no chips, cracks or "hot spots". Stands almost 4 1/2 inches tall by 5 1/2 inch wide. I have another two similar to this and listing a small vase in the same pattern. Happy to combine where possible.
