Dubbed 'Manx Grand Prix' in 1939, what would become the best-known racing motorcycle of all time had become simply 'Manx' when production resumed in 1946, though only the presence of Roadholder telescopic front forks distinguished the post-war bike from the '39 version. The first significant change in engine specification occurred in 1949 when the Manx gained a double-overhead-camshaft cylinder head like that enjoyed by the works bikes, but the major development was the arrival for 1951 of the Featherbed frame that enabled Norton works rider Geoff Duke to take the 350cc and 500cc world titles that year. The cycle parts remained essentially unchanged from then on, apart from the adoption of a double-sided, TLS front brake for 1962. Manx engine development though, continued steadily until production ceased at the end of '62, the most significant design change being the adoption of 'square' bore and stroke dimensions for 1954.
This 'barn find' Manx was acquired from the vendor's late father-in-law circa 40 years ago and was last used around 20 years ago. Apparently complete, the machine is offered for restoration and sold strictly as viewed (close inspection advised). There are no documents with this Lot. It should be noted that the engine number was not stamped at the Norton factory.
