The Brushroll is original, the end caps are different on later models and on genuine replacements, and the belts look old enough, and brittle enough, to be original- I could certainly be wrong about that though. But jfalberti guessed correctly about the major abnormality of this Kirby; it has a Tradition Motor, although he's wrong about the Tradition being the first 240 volt kirby sold in the UK. The Classic Omega was the first, James Sandilands has an original 240 volt Omega, but they're one of the rarest vacuums in Britain, the Classic III is also reasonably difficult to find, although I do have an original UK Classic III, but due to the major rarity of a genuine 240 volt Classic Omega it's a heck of a lot easier to import one from America and switch the motor from a Tradition.
