Trying to figure out if this SFBJ Doll is authentic or a reproduction. It's makred SFBJ 236 Paris, along with Doris Howell 6-19-83 on the neck. She comprises porcelain and I know SFBJ bought out another company in the 1800's, so is this actually a doll from 1883? I couldn't find any info on the artist Howell, so any information would be helpful. Thanks!
