In 2013-2014, this model was released as a Warehouse Model #430003 called Quarter Horse Bay Roan. It is very similar, or a re-release of #1138 from 2001-2002. This model has crisper masking on the face, more blended tail colors, darker or black hooves and a VIN Hoof Stamp. The VIN number and Copyright date on the box is 2013, but model was available for sale in 2014. See separate record for #1138.
Side note: The mold was retooled with a longer tail in 2008, so I would assume this release was using models from the #1138 run. Perhaps they were given updated paint details for the warehouse run.
