Alabaster with white mane and tail. Typically, most Chalky models were made between 1973-1976. See other record for regular release photos.
"This is a Chalky Alabaster Rearing Stallion on a pen set. I'm not sure what company made the set, but the horse is screwed into the base with felt covering the bottom of the base, just like the Breyer lamps (Dunning Industries). Because the model is a chalky, the set most likely dates to the mid-1970s. There is also a Classic Lipizzan on a similar pen set." - Kirsten Wellman
