I thought I'd try my hand at this interesting subject. Gabriel Voisin was a French aircraft designer/manufacturer who turned his hands to producing luxury cars, under the brand Avions Voisin. This race car was built for the 1923 Grand Prix season. Despite some innovative engineering, the car was not successful. Still, being angular in shape, it lends itself well to a paper model
The actual cars comprised of a wooden frame and aluminium panels. Two lengths of the wooden frame can be seen running along the sides, below the cockpit.
