1906 SIZAIRE & NAUDIN SPORT TYPE F
History known since the 1970s
Rare survivor
Mechanical refurbished
Belgian registration
Chassis number : 1126
Early 1903, the Sizaire brothers (Maurice and Gorges) and Louis Naudin joined forces to build and sell a car of their own design. The car is quite powerful with its "big" single cylinder engine of 120 mm bore and 110 mm stroke and more than 1.2 l of displacement for a total weight of 600 kg. However, the transmission had trouble handling the torque of the "big single", and the first customers had a hard time. For the good reputation of the young brand, this had to be remedied: Maurice Sizaire therefore developed a new transaxle, a direct three-speed transmission. At the same time, the front suspension evolved with an exclusive system of independent wheels that ensured perfect road holding. These innovations, which appeared in the summer of 1903, brought rapid success to the company, which moved into new, vast premises in Courbevoie. However, the price of the cars was too low and the company's finances quickly faltered. The Duke of Uzès bought the company and put his colours on the emblem: a red and blue pennant on a white background with the letters SN. The fame of Sizaire & Naudin increases nevertheless with the first victories in races (Coupe des Voiturettes organized by the Auto-Journal, in 1906, 1907 and 1908, Targa Florio 1907 and numerous world speed records). Maurice Sizaire developed a racing model nicknamed the Monstre, with a huge 250 mm stroke engine to get around the regulations limiting the bore to 100 mm. At the beginning of the 1910s, the costly and unproven development of a 4-cylinder engine caused disorder in the company and the Sizaire brothers and Louis Naudin... were dismissed. The company was finally liquidated in 1921. During this time, the Sizaire brothers tried their luck again on the other side of the Channel with a certain F.-W. Berwick. But this is another story. The F-Type we are presenting is one of the very few surviving cars of the brand, and one of the only ones in working order and regularly entered in rallies. It is the 8 HP Sport model with "2 buckets bodywork" as indicated in the original catalogue, equipped with the famous 1,244 cc single cylinder engine. Its history is known since 1975, when it was found in the hands of a Dutch amateur, Mr de Vaal, who restored it cosmetically. In 2003, Christian Mullaert, a great Belgian collector, bought it and started working on the broken and incomplete transaxle.
One of his friends, also a connoisseur, bought the car from him shortly before his death and finished the difficult mechanical restoration. The car is complete with its fenders and spare wheel, and in a superb working condition. Starting a single-cylinder engine of this size being quite dangerous, the car has been fitted with a discreet Mini starter to make the manoeuvre easier. A rare opportunity to acquire an iconic, high-performance "single-cylinder" from the early days of the automobile.
