Hello. My sister has a Roseville bowl or bowl-shaped planter that she is curious about. She can't quite make out the markings on the bottom. She believes it says "KKANS 1400-7" and then "BO11OM" or BOTTOM". She states it could say RRANS 1400-7". I have not done any extensive research, but from the little I have done, I can't find anything with those letters or numbers. Perhaps she and I best go to the library. Does anyone have any information about lettering and numbers-best resources? Thank you. Christinia
