Allen (1913 Ohio automobile) should not be confused with Allen (1913 Philadelphia automobile).
The Allen was an American automobile built in Fostoria, Ohio between 1913 and 1921. The company used 3.1 liter four-cylinder side-valve Sommers engines, and acquired said company in 1915. The 1920 the Allen 43 was made, featuring bevel-sided touring coachwork and a high-shouldered radiator. Ultimately, sales of this vehicle were not enough to avert the company's bankruptcy, which followed in 1921. Willys acquired what little was left.[1] In total, 20,00 vehicles were sold.
