Reviewing he literature and magazines before World War One, Ford was not manufacturing TT trucks. The TT did not come on the roads until after 1918. Mostly from the need of the Army. The majority of those vehicles identified as a truck TT was a Ford car chassis with a wagon bed or platform that could be used as a truck. In some cases, vehicles were bodied with a commercial body. It was not until after 1918 the Ford TT truck was a reality.
Until 1918 and Ford developing a TT, most were Ford car frames up dated with a conversion frame and spring axle combination.
Very cool and interesting. Thank you for this information.
