Hello,My name is ***** ***** I will be the expert helping you. Please use the Add Files feature on your screen to add pictures of the doll and the marks that you have described. Also look on the back of her neck or shoulder for any more marks.
I will opt-out as this mark is not familiar to me. Another expert will step in and answer.
The other expert opted out because she was unable to identify the mark on the doll. I have searched all of my guides on Antique Dolls, and all my sources for antique dolls and have not been able to locate this mark. The only thing for sure is it was made in Germany.
I am sorry but, that is all that two of us know about this doll.
I am also going to opt out, the question will remain on the board. You do not need to do anything else, if someone knows this mark, they will pick this up and give you an answer to your question.
