Kestner doll 164 27"

From the research I have did online I think she is a Kestner doll. She is marked with an L and 15 and says made in Germany 164 on the back of her head. On her lower right back she is stamped in red Germany and 151/2. Not sure if original clothes, shoes or wig. She is overall in good condition. She is 27" her head moves side to side, all of her joints move, wrists also. She has red lines along toes and fingers.The string is also in good condition. She has blue set eyes and open mouth with four teeth.
