The manufacturer�s original playfield drawing (not shown here) is undated and unsigned. The horse names are: Uncle Miltie, Lulu Bell, Whiz Kid, Louie II, Frustration, and Tizzie Liz. A similar version of this game, Williams' 1951 'Nags', is dated one month later but appears to have not gone into production. 'Hayburners' was released again two months later as Williams' 1951 'Jalopy', with an identical playfield design, different artwork, and an auto racing theme.
