In 1979-1980 this model was released as a special run. An estimated 825 models were supplied by Bentley Sales and Mission Supply House. Models are dapple grey with dapples on the head and neck, bald face, gray or charcoal mane and tail, 4 socks with grey hooves and the tail ribbon is yellow with red crisscross. There was a lot of variation on the dappling, and models typically had a semi glossy finish. These models have the 'B' Stamp.
In 1984, as Breyer was leaving Chicago for NJ, an estimated 150 models were again distributed by various companies. These models have the exact same color, pattern and ribbon color. The dapples also appear to have the same wild range of variations. It's possible these 150 models were leftover models from the initial run, and being cleared out for the move. If so, they should also have the 'B' Stamp.
