This model was released in the Series III Stable Estate Playset #3987. Set included 4 Horses and 37 Accessories. The Series III models had a very short sales run as there were production issues with Creata International.
This set was considered a Special Run or Collector's Edition, and produced by Creata International for Specialty Market stores (smaller retail stores). Breyer purchased the mold and accessories in 2004.
Model colors and molds can vary from the catalog photo in these sets.
