The four Ceirano brothers, Giovanni Battista, Giovanni, Matteo and Ernesto, were leading pioneers in Italy’s motor car history. Giovanni designed the “Welleyes”, from which the first Fiat sprang, and one brother or another sired a host of marques over the course of some twenty years: Fratelli Ceirano (1901), Itala (1904), STAR (1904), Junior (1905), SPA (1906), SCAT (1906) and Ceirano S.A. (1919). The 5 HP was made by Fratelli Ceirano. It has an Aster single-cylinder engine and a patented four-speed, constant-mesh gearbox. Note the two radiators at the sides. The “duc” coachwork is by Locati & Torretta.
