Firstly, the “Marshal” name had a prewar three-axle truck, which production was stopped in 1941. The next time the “Marshal” name appeared only in the early 60s to refer the three-axle medium-duty trucks. The models are equipped with Park Royal cabins. There were GM6RAS (6×2) and GM6RAT (6×4) versions.
