The Type 38 was produced in 1926 and 1927. It used the 2 Litre (1991 cc/121 in³) engine from the Type 35A "Tecla".
The supercharger from the Type 37A was later fitted, making the Type 38A.
Its gearbox and brakes were later used in the Type 40, while its radiator and axles were shared with the Type 43.
385 examples were produced, 39 of which were supercharged 38As.
