Unknown Orgin or make bisque doll very old?

I found this doll at ta little thrift store in a small country town. This doll is hand painted, she has a working music box inside her cloth back. She is porcelain/bisque upper torso that has two tiny holes that sews that torso to the cloth body. Her hands and feet are porcelain/bisque as well. She has felt shoes, and leggings underneath her dress. Her nails are painted to match her lips and dress. She is in excellent condition, I would love to know where she orginates and who makes her. What era, all the above. Any help would be appreciated. I have never seen another like her... Thanks
