The "Twelve" in the name referred to the taxation horsepower rating in the United Kingdom.
The Twelve-Six was powered by a 1476 cc six-cylinder side-valve engine and was available as either a four-door saloon or four-seat open tourer.
The de-luxe option gave the owner all round safety glass, leather upholstery and bumpers.
The car had a separate chassis that was conventional using beam axles and semi-elliptic leaf springs all round and hydraulic brakes.
After World War II the car was re-launched in 1947 as the Super Twelve with the drophead also still available.
