Bay Overo with 4 stockings and grey hooves. There was a leg up and leg down version, meaning the front left leg was raised to be nearly parallel with the head. This caused the model to be unstable and shortly after the first releases, the mold was retooled to lower that leg.
In 1982, JC Penney sold this as a single model (671-0396) and with Western tack (671-0388).
There is a 'Peach' color variation, but from the models I've seen, these look like shrinky models, where the plastic is starting to break down and causes the model to shrink. Some models have an oily discharge, and a common problem is the color greatly fades.
