WANTED white body with Silver rim, blue lines and silver leaves - faint crown stamp:- I am looking for any pieces of this design. I have no idea who made it, but it belonged to my Great Grandmother who died in 1940. All the pieces have a white/ivory body with a silver rim, light-blue lines and silver leaves. Some pieces have a silver letter and blue number painted on the back, as simple as L and 5, but not all pieces have the same. One piece has a very faint 3 point solid crown on the back.
