Following its 1946 launch Sunbeam's futuristic shaft-drive S7 did not sell in quite the expected volume but, after the modified S7 De Luxe arrived in 1949, sales did indeed improve, possibly assisted by the firm's same-time intro of the more conventional S8. During a brief post-war lifespan Sunbeam manufactured a respectable total of around 16000 S7/S8s, albeit many potential customers deemed the 2-model range was always too high-priced and over-engineered. Sadly, BSA's board of directors, who'd purchased the prestigious brand from AMC during WWII, called a halt to production in 1956. In recent years however Sunbeam's ohc twins have become increasingly popular, undoubtedly helped by the availability of parts and technical support provided by Stewart Engineering, one of the first sole-brand specialists, established in 1960.
After its acquisition in stripped condition two years ago, there began a no-expense-spared restoration, with countless new parts [outlined below] sourced from Stewart Engineering. The vendor also ensured that all the original tin-ware was indeed of pressed steel. He also confirms that the unhurried but comprehensive rebuild included a complete rewire [with electronic rectifier/regulator]; plus a Stewart alternator; a refurbished & recalibrated speedometer, now showing about 80 post-workshop miles; a new carburettor; all bearings checked with new seals and gaskets throughout; plus a new set tyres. Visual inspection reveals an immaculate machine, presented as in a local friendly Sunbeam dealer showroom, almost 70 years ago!
Taxed until February 2020 an accompanying ring-binder contains a V5 & V5C, a VMCC Dating Certificate, previous MOTs, and other relevant history.
