Identifying A Porcelain Doll?

I just got this porcelain doll and I am very curious about when it was made. I searched the internet and did not find anything. This doll has a stamp on the back of her head and this is the only branding marker on it. In terms of dimensions, it is about 63 cm tall and 39 wide. While most dolls are stiff, this can be moved as it has flexible joints.

If there is any information you can help me with, I will be very grateful.

Thank you in advance and have a great day!
