Strictly a special order item, with King George V and Queen Mary among the customers. Chassis much as before, though long wheelbase cars only available: fluid flywheel and vacuum-servo brakes, of course. Detachable-head pushrod motor gives 140bhp, but as the end-product's likely to weigh three tons, this is academic. No known survivors with the correct engine.
