Not sure of the "U" number on this one. Large triple petticoat, approximately 7 " in base diameter and 5" tall with a 1/2" of inner skirt extension. Recessed-embossed "S, B in an oval, T on the skirt. There is another set of numbers on the flat part of one of the ears, but I can't make it out. The only defect I can find on this is a small glaze missing spot on the very tip of one of the ears. Weighs over 5 pounds. Nice shape. Will ship at actual cost, or will deliver to Springfield in November.
