The MAC was Velocette's 350 cc overhead-valve single, created by lengthening the stroke of the cheaper 250 cc MOV. It became the bread-and-butter Hall Green model, known for dependable running and good handling rather than outright speed. This pre-war version used girder forks and weighed about 130 kg.
