In 1998, this model was released in the Mare & Foal Series 2 - Morgan #3955. Set included a Light Grey Cantering Morgan and Chestnut or Palomino Prancing Foal. This set was considered a Special Run or Collector's Edition, and produced by Creata International for Specialty Market stores (smaller retail stores). This set has the same pattern, but different color, as the previous Mare & Foal set.
Side Note: This foal looks the same as the one in the previous set...(?)
