The Mk 1 proved the idea — five tonnes across country and across water — and the Mk 2 that followed was built in seven times the numbers.

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.
