The Living Horse Series was a lower priced model that was packaged in a window box with suede pads around the ties that attached the model to the box. These models were still produced at the factory in IN.
Bella, Indigo Rising, and Honey Magnet all had pre-production releases. I believe not more than 50 of these pre-production models were released. These pre-production versions all have a different plastic consistency. They are lighter and don't feel as 'durable'. They also 'creak' when you apply pressure to the sides of the model.
