13-string Koto, vintage art piece. Price negotiable.

This is a koto that my mother used to play.
She hasn't played it much recently, so I've decided to list it here.
It was purchased 40 years ago and has various intricate details added as a work of art, so I believe it's a koto you don't see very often.
As it is vintage, there is some age-related deterioration.
