From Breyer Molds and Models 5th Edition by Nancy Atkinson Young:

"The models white-plastic body is coated with a wash of white paint, which gives him a chalky appearance."

"#983 portrays a real Arab race horse named "EQUUS", namesake of the horse magazine Equus. The July 1997 issue carried a photo of the Breyer along with an article titled "Equus Immortalized." "Long-time subscribers to Equus", says the article, "will remember reading about the upbringing and education of an Arabian colt who bore the magazine's name. To celebrate his, and the magazine's 20th birthday this year, Breyer Animal Creations has released a limited-edition Equus model that captures the horse in his prime years as a racehorse....Bobbie Lieberman, a founding editor of the magazine and Equus' breeder, remembers how her horse and the magazine became linked forever...Equus was foaled in May 1977, and Lieberman chronicled his upbringing in a regular column for several years." The remark that the model is a limited edition is incorrect; it is an ordinary regular run."
