One of the many firms prospering during the post war building boom in Oklahoma City was the Kiowa Lumber Company, led by president Albert L. Mason and general manager H.D. Leonhardt. In 1919 Mason bought this airplane bungalow from G.A. Nichols while Leonhardt built the home next door to the west. Although Mason died in 1931,his widow, Katherine, remained until 1965.
