Italy was coming out of the Second World War, trying to rebuild in entirety. There was a need to improve efficiency of work done and Mario Musso, an innovative mechanic assembled a 6 HP petrol engine to be coupled to a concrete mixer or a winch, to fill the needs of masons for lifting loads and to mix huge quantities of concrete. He found ways to reuse damaged war plane parts ( cylinders, pistons,etc). He improved fuel efficiency so much that 2 litres of petrol was sufficient for 8hours of work. His work was patented and all cement mixers, all hoist-lifts of the Piemonte Region were working with a Musso engine.
