Identifying a Porcelain Skater Doll?

I've recently come into possession of a doll I can't identify and I'm hoping you can help. I think she's vintage because her outfit is sewn onto her and the white fur trim on the dress, hat, and muff are made out of real fur. She's porcelain and her eyes appear to be glass. Her mouth is open and her tongue looks dimensional. There are some markings on the back of her neck and one seems to be made by hand. She doesn't appear to have been played with, but is disheveled. I'm hoping this will help you identify her for me.
