hiya, I have been trying to do some research on this doll and cannot find her identity.

I hear that Kestner dolls can have an x or xi on their heads as markings, this lovely doll has a mark deep down on her lower neck that looks like a cross or an x.

She also has the number 11 in the mid back of head and the number 8 on the top back of head and body also, can anybody shed any light, she is 24" long. Thank you
