This is the #42 Brown Pinto Western Pony in set #542 'Kit Carson'. (See separate record for #42 model details). A dark brown plastic cavalry style saddle was released with this set. This saddle has molded on saddle blanket and bedroll with a pull-through cinch. Same saddle that was released with Davy Crockett.
Kit Carson has dark brown or black hair, light tan or grey jacket and dark brown pants and moccasins. He came with a removable hat, neckerchief, rifle and knife. There are two different variations of the knife, one released with the Indian, and one released for Crockett/Carson - see photos. Kit Carson and Davy Crockett are the same mold, sculpted by Chris Hess, and have no mold marks or Copyright stamps. One significant difference between these two molds, is Kit has a groove cut into the underside of his right hand to help hold his rifle.
