Hildegard Gunzel Vintage Collectable 75 cm doll!

I am respectfully selling some very Collectable dolls for a friend. They belonged to her late mother who paid in the region of R7000.00 each in the the 1980's. I did as much research on the dolls as possible but if I make a mistake with anything or you may have any additional information please let me know. This doll is "Sahra-Richel" by Hildegard Gunzel, head number restricted to 750, so it is a Limited Edition doll, she was made by the Waltershause doll factory in Germany in the 1980's. She measures 75 cm, has blue grey hand blown glass eyes, human blonde hair and beige colored checked Dipion silk dress with decorated collar and bow, Cambic lace underwear cotton stockings and leather shoes. The suggested internet price for such a new doll is $1000.00. I believe the older dolls sells for far more. She has her original tag also. This is the first time I've seen such a doll and what can I say, the most beautiful attractive dolls I've ever seen!
