I was perusing the '62 Raleigh catalog when I came across this marketing description of the versatility of the Superbe's Dynohub;
"..built-in Dynohub generator lighting--ideal for emergency lighting in your fall-out shelter." Elsewhere in the catalog, the Dynohub is described as "Handy in case of National Emergency." Perhaps you would remove the fork from the frame to make a Dynohub flashlight?
WWII was only 17 years in the grave at that point, and it would still be very much on the minds of the Brits, and the Cold War was at its peak, but it's hard to imagine someone holding up the front end of a Superbe, spinning the wheel and casting a flickering glow at a shelf of cans, looking for some whole-kernel corn.
