The British 6x4 cross-country lorries were made by various companies under specified standards. But real standardisations did not exist. The illustrated vehicle is a Karrier CK6 6x4 GS.
There were breakdown, bridging and workshop variants based on the Karrier CK 6 besides the illustrated GS version. The Karrier CK 6 was propelled by a four litres, six-cylinder engine with a power of 80 HP.
