Initials of Società Ceirano Automobili Torino, a company founded in 1906 in Turin, by Giovanni Ceirano, who had just left Junior. It was an inventive and dynamic company that patented many innovations before the competition, for example the compressed air automatic starting and the steel dismountable wheels. It also suffered the difficult economic situation after WWI and in 1925 its capital was restored thanks to the contribution of Giovanni Ceirano, who had left some years earlier. The 150 is from that period, with a line inspired on the Lancia Lambda. But in 1929, the adhesion to the Fiat Consortium, an body created exclusively for the production of industrial vehicles, put an end to the car production. In 1932, it was acquired by Spa.
