This extremely rare OM is one of the coveted 2.3-litre supercharged cars that were used only in competition and were not offered by the Italian marque as an official production model. 
Chassis number 6651095 was part of an OM team that was put together in 1930 by Edgar Fronteras and the marque’s British importer, LC Rawlence & Co. They planned to enter the Irish Grand Prix at Phoenix Park in July that year, and then the RAC Tourist Trophy, which would take place the following month on the Ards circuit near Belfast.
