3.7cm FlaK 36 auf Fahrgestell Zugkraftwagen 5t (Sd Kfz 6/2)

History: The Büssing-NAG BN9 (Zgkw 8t) was built from 1939 to 1943, and was used as the basis of the self-propelled 3.7cm FlaK36. The rear superstructure of the vehicle was specially designed for the FlaK gun so that the sides folded down to provide an adequate platform for all-round traverse. Ammunition for the 3.7cm FlaK was carried in a single-axle trailer behind the Zgkw 8t. When the latter was phased out of production in 1943, the 3.7cm was mounted on the Zgkw 8t, as a temporary solution. The sWS was intended to carry the 3.7cm FlaK43.
