I have been unsuccessful in finding other examples of these Wedgwood dinner plates. Pattern number A7415, they are a pale blue with a pattern in pink luster. The pattern is reminiscent of 19th century designs, but the incised code on the reverse indicates a date between 1924 and 1929. They are also incised Wedgwood and Made in England. 9 7/8" across. No chips or cracks. There is some very minor wear to the luster decoration.
There is a fourth plate with more substantial wear which I can include.
