The White Armoured Car (
AutoMitrailleuse White in French service) was the French equivalent of Britain's Rolls Royce armoured car, inasmuch as it was a World War One design that was continually upgraded and in service until World War Two. It was based on an American White chassis, and mounted a Hotchkiss machine gun and a 37mm gun opposite each other in the turret.
This is my 1:100 (15mm) 3d printed model in WSF nylon, available for sale in this material or in high-resolution FUD resin at
