Officine Meccaniche (OM) was an Italian car, truck, tractor and locomotive manufacturing company, founded in 1899 in Milan as Societa Anonima Officine Meccaniche (SAOM).

The inception of the company had resulted from the merger of two companies,Grondona Comi & C and Miani Silvestri & C. Originally, OM manufactured railway stock. Car production started in 1918, using the plant of the former Brixia-Zust (Brixia-Züst), just after OM took over the Zust car company of Brescia, Northern Italy.

Fiat take-over and post-war years

OM was taken over by the Fiat Group in 1938 and in the following year passenger car production ceased, and OM became a commercial vehicle and train part manufacturer.

Main new product in the WWII post-war era was the Leoncino (1950) a light truck in the 2.0 to 2.5 tons range, which was an immediate success. It became the forefather of several series of heavier but structurally similar models, namely Tigrotto, Tigre, Lupetto, Cerbiatto and Daino, launched between 1957 and 1964. Bus chassis versions of several of these models were also available.

In the 60s and 70s the light and medium-weight OM truck ranges were sold in Switzerland as Saurer-OM or Berna-OM, in Austria as Steyr-OM, in France as Unic-OM, and in Germany as Büssing-OM.

The end of OM

In 1968 OM was definitively merged into the Fiat Group as a brand belonging to the Commercial Vehicles division, which also included Fiat and Unic.

In 1975 it was absorbed (as part of the Fiat Group) into IVECO and the OM brand disappeared from the truck and bus markets, although it still survives as an independent forklift manufacturer.
