The Morris CDSW 6x4 was a six-wheeled artillery tractor brought into service in the early to mid-1930s by the British Army to tow its field guns.

[1][2] Typically it was used to pull the 18-pounder field gun and the 4.5-inch howitzer, and later the 25-pounder gun-howitzer which replaced those two weapons.

It was also used, with a modified body, for hauling the 40mm Bofors in the Light Anti-Aircraft (LAA) regiments.

It was for the large part replaced in its primary role towing the 25 pdrs by the Morris C8 "Quad".

[1][2] CDSW indicated model "C", Double Axle rear "D", Six Cylinder Engine "S" and Winch "W".
