The Ford Model TT was a series of trucks introduced in 1917 that were based on the Ford Model T. The TT featured a more robust frame as well as rear axle. The Model TT shared its 2.9L inline four with the Model T, and was available in a variety of purpose built body styles from a number of builders. Starting in 1924, Ford began to offer its own truck bodies. Production of the Ford Model TT lasted until 1927.
