At the beginning of the century, Delaunay-Belleville was one of the most, if the most desired French marque. Emphasis during construction was placed on fine materials and craftsmanship which attracted the pillars of society. Customers to Delaunay-Belleville included King Alphonso XIII of Spain, King George I of Greece and Czar Nicholas II of Russia
S.A. des Automobiles Delaunay-Belleville was formed by Marius Barbarou and Louis Delaunay in 1903. Delaunay married into the Belleville family who owned the boiler making company of St. Denis. This relationship was reflected on the styling of Delaunay-Belleville cars with the engine surrounds on many examples capturing the character of the boiler company.
Marius Barbarou was responsible for much of the styling and design of the cars. He had previous experience working for Clement, Lorraine-Dietrich and Benz and was directly responsible for the 1904 Paris show car. He helped adopt the Belleville patented system of lubrication to internal combustion engines. This system was one of the first to use a pressurized system of pumps and oil ways instead of the common drip system used during the period.
Chassis 1406V, the Roi-Des-Belges Tourer
Chassis 1406V was ordered by Sir J. Milne Barbour Bart of Ireland. It was bodied in England by Mulliner having English, rather than French accessories . As discovered by the Delaunay-Belleville registrar, this car was the first to receive a six cylinder engine which would become a defining feature of Delaunay-Belleville cars.
