Alabaster with grey mane, tail and hooves. This model has remained pretty much unchanged, except for the packaging from 1975-1994. From 1975-1987, this model was issued as #5017. She was discontinued for 1988, then from 1989-1994 she was released as #5130, and in the Stablemate Assortment Set #5600 from 1990-1994. These models were made from the heavier Cellulose Acetate plastic, except from 1992-1994 when they were made with the ABS plastic.
Released through Sears in 1989 as the Stablemate Assortment I (or 12-Piece Stablemate Set) #495600 (Sears #49-37902). This set included an alabaster Arabian Mare, steel grey Arabian Stallion, red roan Citation, dapple grey Draft Horse, palomino Morgan Mare, chestnut/red dun Morgan Stallion, red bay Native Dancer, black Saddlebred, red chestnut Seabiscuit, buckskin Silky Sullivan, blue roan Swaps and a dark/medium bay Thoroughbred Mare.

Notice the white Stablemate card shows Reeves Intl in New Jersey on the front, and Breyer Molding Co in Chicago on the back. Even though Reeves purchased Breyer in 1984, packaging remained like this through 1989.
