My Dad has been working on my 1972 Kirby Classic 1CR, and he found quite a few flaws with it until then undiscovered!
Among them:
A missing speed switch insulating tube.
A bent armature cooling fan.
I plan on replacing the following before operation (metal fan already included):
Nozzle seal ring
Screws for front clamps and front bearing plate.
Fan case to motor housing screws.
In the future:
Front and rear motor bearings.
Carbon brushes.
