One of the most charismatic model names in motorcycling history, 'International' was first used by Norton for its top-of-the-range sports roadster in 1932. The Inter's overhead-camshaft engine had been developed in the works racers for the preceding two years, and although (in the case of the '500') it retained the classic 79x100mm bore/ stroke dimensions and shaft-and-bevels cam drive of the existing CS1, was entirely new. Based on the works bikes and intended for racing, the International could nevertheless be ordered with refinements such as lights and a kick-starter equipped gearbox. By the time production halted in 1939 it was being built with a four-speed foot-change 'box and plunger rear suspension (the 'Garden Gate' frame), reappearing after the war in similar guise save for the adoption of the hydraulically-damped Roadholder front fork, which replaced the pre-war girder.
The Inter would remain fundamentally unchanged until 1953 when it gained the race-developed Featherbed frame, an all-alloy engine and the 'laid down' gearbox. Expensive to make and challenged by cheaper parallel twins of comparable performance, the Inter ceased to be catalogued after 1955 but could still be obtained to special order until 1958, many of these later machines incorporating Manx components.
Owned by the vendor since 1995, the pre-war Inter offered here is a nicely patinated older restoration that would benefit from a detailed clean. Last taxed until May 2012, the Norton carries a rally number for the Isle of Man Section Vintage Motor Cycle Club TT Mountain Challenge where it was entrant number '91'. The engine turns over.
