Vintage Baby Crissy Doll 23" Hair Does Not Work

PLEASE READ DESCRIPTION.
1972 Baby Crissy Doll. Beautiful doll, there is a very small discolored spot on lip and on cheek. Hair does not work, pull string is extended and does not seem to retract...hair is short as pictured all around, about shoulder length. Around where the string retracts there is a small tear. You can also hear the parts that used to make hair retract moving around inside when you pick her up. PLEASE LOOK AT PICTURES AS THEY SHOW CONDITION.
**THIS DOLL IS PROPPED FOR BETTER PICTURES. SHE DOES NOT SIT UP ON HER OWN.
