The set included Ben Cartwright's Buck (Buckskin Ruffian), Adam Cartwright's Sport (Chestnut Black Beauty), Hoss Cartwright's Chubb (Bay Duchess) and Little Joe Cartwright's Cochise (Black Pinto Warmblood Stallion). Color could also be a dark bay pinto.
The model advertised in JAH included the Classic Ginger instead of the Warmblood Stallion. Still researching if that mold was ever released in this set.
