The M-series Studebaker trucks came in several versions both pre and post WW II.

While only pickup beds were offered on the M5, M15, & M15A versions from the factory, combination cab and rolling chassis were sold, allowing custom truck body manufacturers to variously sell standard beds and boxes or custom fabricate them to an owners specifications.

engine, through the use of a different fire wall on these cabs, all the other front sheet metal stayed the same.

The M series truck range was produced from 1939 to 1942, when civilain production was stopped due to the Second World War and restarted in 1945, continued until 1949.

The M series sported a more aerodynamic shape than most trucks of the time, with easily recognisable "wind wing" vents on the driver and passenger windows, a feature not found on any other make of American truck during World War II.
