Vintage Rocking horse

Bought this from a couple and paid 100.00. Said shes owned atleast 20 yrs but thinks it could be between 20-30 yrs old, but she wasnt too sure. It seems to be made of carved wood, metal wheels and stirrups, horse hair and leather saddle.Im not sure if this is a sears robuck reproduction from possibly 1987 or an antique. It does seem to be in really condition for its age of atleast almost 30 yrs, if thats the case. Im wanting to know if this is a replica or not. How old os it? How much would somthing like this would be worth?

Good
