The vehicle was based on a Morris Commercial C9 4x2 15 long cwt (760 kg) truck chassis.

On this chassis, a riveted hull was mounted with an open-topped two-man turret.

Thirty-eight of these cars were used by the 12th Royal Lancers in the Battle of France, where all of them were destroyed or abandoned.

It was found that, when fitted with desert tyres, the vehicle had good performance on soft sand.

The vehicle was retired halfway through the North African Campaign.
