From publisher blurb: Six-Guns: Lawmen - The Earps & Mastersons features six character descriptions and statistic blocks for Sidewinder: Recoiled, although these six lawmen could be used in any Wild West roleplayin' game. We've gathered a posse of three brothers from two of the most famous families of the Old West: Wyatt Berry Stapp Earp. Morgan Seth Earp. Virgil Walter Earp. Bertholomiew (William Barclay, W.B.) "Bat" Masterson. Edward "Ed" Masterson. James "Jim" Masterson.
