OSI, acronym for Officine Stampaggi Industriali (literally "Industrial Stampings Workshops") was a coachbuilding company founded in 1960 in Turin by former Ghia president Luigi Segre (1919–63) and Arrigo Olivetti (1889–1977) from the Fergat company, a manufacturer of automotive components.
[3] The short lived company made some custom built cars based on Alfa Romeo, Fiat and Ford models.
One of their first contracts was to build the bodyshells of the 1961 Innocenti 950 Spider, designed by a young Tom Tjaarda at Ghia's behest.
[5] Segre died after complications following appendicitis (variously reported as an infection during recovery after successful removal of kidney stones) in 1963, leaving the rising company without its personal link to Ghia and Ford.
[2] Bianco was fired and Sartorelli was charged with winding down operations, incorporating the OSI design office with that of Fiat's in May 1968.
