vintage jointed bisque china doll marked Germany, girl doll w/ glass eyes

This doll is marked Germany, but I'm not certain of exact age. I think this is possibly a 1980s vintage reproduction of an antique doll?

I'm just guessing that from other pieces from this estate, but I know very little about dolls - and this did come out of the estate of a doll collector / restorer, and it's possible this is an old doll with a newer wig. She's at least 15 to 20 years old, I know.

She's about 10 3/4" tall overall, in very good clean condition. Joints are snug, and work smoothly.
