Plans of a sidewheel steamer, Oneonta. The plans may be a depiction of the steamer Oneonta built in 1863 and operated by the Oregon Steam Navigation Company, but features in the plans differ from contemporary photographs of that steamboat. It is unknown whether the drawings are originals or later reproductions. The drawings consist of 3 plans on 1 sheet: a top view, a side view, and a plan of the pilot house and rooms. Sheet is stamped: "Oregon Historical Society - Portland, Oregon / from collection of L. C. Hosford."
