Non-custom chip bodies for the DAH program. 50 of each mold were released in 2012 and in 2013 there were several open runs in 2014 and 2015. A hand written date should be written on the underside of each model - DAC 2012, DAC 2013 (or something similar). DAC stands for Design A Chip.
A standard brown cow was available until 2015, when a black calf was released. Was only available when purchased as a set with the Cutting QH.
