bought and sold by other engineering firms. In the early 1970s the Vincent Owners Club created via public subscription the VOC Spares Company Ltd to ensure continued availability of spares. The company is independent of the club who retain a majority share holding. Subsequent developments Norvin Vincent engines have been fitted to other frames. The most common was the Norvin, using a Norton Featherbed frame. Other names were used, including Vincent–Norton, Vinton, and Vin–Nor. Whereas most were one-off builds, an early attempt at production was announced by Staffordshire engineer Tom Somerton in late 1959, with an intended low-volume run from 1960. It's not known how many were completed. New Norvins were announced by Hailwood Motorcycle Restorations in 2008, a brand associated with David Hailwood (Mike Hailwood's son) and bike restorer John Mossey. The business soon was dissolved. The Norvin is now available from John Mossey under a new brand, JMC Classics, together with the Egli-framed Vincent. Fritz Egli Fritz Egli, a specialist frame manufacturer based in Switzerland, produced an Egli-Vincent, and around 100 were produced between 1967 and 1972. Egli-Vincents were subsequently built under licence in France by Patrick Godet and Slater Brothers in the UK. JMC Classics also produce new Egli framed Vincents in UK. Vincent RTV Motorcycles In 1996, a new motorcycle company was formed by three individuals, Rodney Brown (a metallurgical engineer), Terry Prince (a Vincent enthusiast and specialist) and Ron Slender. Brown provided the financial start and along with Prince were the founding directors, with Slender specialising with business development post-production. The company was named RTV Motorcycles. Its ambition was to produce a modern-day classic Vincent motorcycle that could be marketed, in reasonable volumes, worldwide. It used a redesigned and modernised version of the Vincent engine, engineered by Prince, with an increased capacity and in an Egli-style frame. The motorcycles were to be built individually by hand. The range was to include both a touring and sports model in capacities of 1,000 cc (RTV1000) and 1,200 cc (RTV1200). Complete new engines would also be made available for separate purchase. Production was initially to begin for the larger capacity machine designated the RTV1200. These were to be fitted, as standard, with state of the art Bosch electric start, Brembo brakes, adjustable Paioli upside down forks, Ohlins rear monoshock and V-2 multiplate clutch. The first factory prototype RTV was built in 1998; other RTV prototypes were in various
