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 '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. Bought from South Africa, this 500cc Manx is reputed to have been owned and raced by famous South African privateer Paddy Driver. Driver arrived in the UK in 1958 and raced Nortons initially. Later he switched to Matchless and enjoyed his most successful season in 1965, finishing third in the 500cc World Championship behind Mike Hailwood and Giacomo Agostini. The machine's engine is reportedly the last overhauled by famed Norton tuner Joe Ryan before his death in August 1996, and incorporates a number of up-dates including coarse-pitch cam drive bevels, coil valve springs and 1961-specification piston and cams. We are advised that both valves and the exhaust valve seat are new, and that the big-end has done circa 100 miles since last replaced. Other sensible improvements include a Bob Newby belt primary drive and clutch. Finished in silver/black, the machine has the four-speed gearbox and is described as in good condition throughout. It is hoped that further information about its racing career and date of last use will be available at time of sale.
