Hi Redneckvacman:
Welcome to Vacuumland.
I have one of these, but it's older the tube between motor and bag is longer and there's no handle, and the bag is longer too, without the wire frame. Mine has the brush roll, and belt, the cord is original, but I don't use it as there are several breaks.
Where to get a brush roll? Try contacting the Cleveland Wood Products company in Cleveland, Ohio. This company makes brush rolls for almost every brand, and they specialize in the bags for Kirby. CWP might be able to customize a brush for you, or help you locate one that could fit.
Good luck in your search,
Alex Taber.
