Wim from Belgium sent me pics of the c1938 16H Norton he rebuilt together with his father. Wim's father had known the bike for decades before he could persuade the owner to part with it. The previous owner had used the Norton to power a woodsaw; the rear wheel had been removed and the rear chain connected to the sawing table. A hole had been chopped in the primary chain case to run a ventilator, via a belt, to supply the engine with cold air. Restoration was still quite straighforward. Nice one, Wim!
