Black with no white markings and grey hooves. Released as a single model called Thoroughbred Racehorse #5177 from 1995-1997 and part of the 12 Piece Stablemate Assortment set #5900 from 1995-1997. The Copyright date on the package is 1994, but released as 'New' in the 1995 catalog.
Model looks the same as #5986, so overstock of this model could have been used for that set.
