Bru popular Head Porcelain Doll

I am not sure if the body to this doll is Bru, head does says Bru J with some numbers someone had scratched under the Bru signature. Bought this wonderful porcelain doll at an estate sale where the women repaired porcelain dolls. Loved the face and hairdo. Doll is all porcelain and is 15" long. Dress is a little dirty, but popular has lace underwear and even nylons. In excellent condition.
