1980 Midnight Horse

Barbie Doll accessory horse is marked Mattel 1980 USA. It's black with four white socks and blaze. It is wearing a removable bridle. Measurements: 11" tall x 10.5" long x 3" wide. Item has been played with, so see photos for condition. It may not be the original bridle. (I consider this horse in good condition, nothing broken.)
