The newly designed truck was designated CS8, (S denoting 6 cylinder and 8 standing for the wheel base of approximately 8 feet ) it had a short stubby appearance with a high ground clearance.
The original CS8 design evolved into three Series, the Mark I, II & III.
The early CS8 had a small windscreen and canvas doors. These were replaced by a full windscreen and metal skinned half doors in 1941.
The CS8 became the workhorse of the British Army and many fell into German hands at Dunkirk, Crete and North Africa where they were equally welcomed as a fine example of British craftsmanship.
