I have a cake plate and 5 smaller plates from the Edwin M. Knowles China Co. From what I have learned, it was produced in October, 1940. But there is no pattern name on the back...just the 40-10 and under that written in gold, "Warranted 22 carat gold". The outer edge of the plate has a band about an inch wide of gold, with a pattern in it. The center has a motif of flowers. I wonder if anyone would know how I could obtain one more small plate? Thank you.
