Butterosi (France) - AllCarIndex

Despite its Italian sounding name, the Butterosi was manufactured in Boulogne-sur-Seine, five miles west of central Paris. The car was powered by a side-valve four-cylinder engine of 1,327cc. There were three body styles: a two-seater roadster, a tourer and the closed saloon.
Notable features were few, but included a combined magneto and dynamo and unit construction of the engine and four-speed gearbox, with the multi-plate clutch fully enclosed by the clutch-pit but accessible through a big rectangular cover-plate. The braking used the same drums for both pedal and hand brakes - the pedal worked external brake-bands and the lever operated expanding shoes.
