The La Nef company were formed in France in 1901 and produced a 3-wheeler called Larcroix-de Laville. The vehicle had a single cylinder De Deon engine which drove the rear wheels with side belts, steering was by a tiller to the front wheel.  As the rear seats were enclosed from the side of the car the passengers would climb aboard through a central door built into the rear panel of the body. 

La Nef stopped producing the vehicles just two years later in 1903.
