Antique Kestner ? Flat top blue eyes German China Head Porcelain Doll

Hi, Up for sale is antique porcelain china head doll.  I think it was made by Kestner.  It is about 21" long.  It has lots of wear from age and use.  The dress has tears and some old repairs.  There is one leg that was replaced and partially repaired with a piece of wood.  The head has light scratches and paint loss.  It is about 5.5" tall x 4.5" wide x 3" deep.  The head and the right leg do not have any chips or cracks.  She has leather shoes that are in good condition with a lot of wear.
