Models had various socks but one prominent sock on the back left leg. These models are very similar to the #5026 release, maybe lighter or pink colored hooves, and some models are more of a darker red chestnut color. Released as a single model #5141 from 1991-1994, and available in the Stablemate Assortment Set #5600 from 1991-1994. These models were made from the heavier Cellulose Acetate plastic, except from 1992-1994 when they were made with the ABS plastic.
In 1995, this model was released with a Jessica Doll made by the Götz company. Included the regular release Arabian Stallion #5120 and Thoroughbred Mare #5141. Models were discontinued in 1994, so these were probably left overs. Unknown if this release was the old or new plastic.
