The record

The contract specified riveted armour; Guy proposed welding, developed rotating jigs for the hulls and turrets, and offered to stand the cost of the first batch if the welds failed. They did not, and the Royal Commission on Awards to Inventors later recognised the technique. Guy lacked the capacity to build the car alongside its artillery tractors, so the design went to the Rootes Group, whose Karrier division built the Humber Armoured Car on its KT 4 chassis with welded hulls and turrets from Guy. Six Guys went to France with the BEF and were lost there; others served with British, Belgian and Dutch units in Britain until 1943. The Tank Museum at Bovington holds the only survivor.

AI rendering impression

An AI rendering impression starts from a 3D model of this vehicle, which an image model then paints into a scene. It is an artist's impression of the type, made to give a feel for the vehicle in its element — not a photograph, and not a record of any particular vehicle.

Proportions, fittings, markings, colours and the setting can all drift from the original in the process. For the vehicle's actual details, rely on the specification, the photographs and the cited sources on this page.
