I've lost track of which firms have been mentioned. Have we had Rudge, Sun and Norman whose motorcycles one still sees from time to time? And if we go back further, early motorcycles included Ariel, Bradbury, Coventry Eagle, Eadie, Excelsior, Hillman, Humber, James, Matchless, New Hudson, Quadrant, Riley, Rover, Singer, Triumph. I must have forgotten some. You'll notice seven car makers there as well. In the early days, cycle shops who may or may not have made their own frames would retail under their own name, powered two wheelers from the mysterious Continent but I think it would be stretching things to include those. Oh, and Rotrax, of course, made speedway bikes.
As to the gun connections, didn't Eadie buy a company that had a contract with the Royal Small Arms Factory at Enfield Lock to make rifle parts? As a dyed in the wool Victorian opportunist, he appropriated the Enfield name and later added 'Royal'. Have I got that right?
