Both these photographs depict Roy Reece. The Norton in the pic on top appears to be a Model 9, note the absense of gearbox and the belt drive. It's an early 1920s model I would guess. The norton in the bottom pic appears to be a 1924/25 model 16H.
Is the later model sublime and the older one rediculous? The older bike has a decently fast engine combined with an almost complete lack of brakes; probably the reason for the mangled front mudguard!
