Mason and Brown were motorcycles produced from 1904 to 1906.
Howard's patent motorcycle
Making their debut at the late Stanley show, these machines differed from their rivals in that the engine was fitted well above the bottom bracket, with the cylinder laid down to point forward. Inside there was a one-piece crankshaft with adjustable ball bearings. There was no carburettor as the action of the inlet valve was said to do away with the need for it. Control was by a single lever with ducts around it for the air cooling.
There were two sizes: 2hp Minerva engined weighing 75lb/34kg and 3hp weighing 95lb/43kg. Both had direct-belt drive, rigid forks and cycle-rim front brake.
