So far the priginal parts on it are the six blade fan, the red belt lifter with Jim Kirby's real signature engraved on it, the grey nozzle trim, the metal part of the hand grip, the grey emptor tray, the black cord isn't an original one from the 40s and is brand new but I still call it original because it's black like the original. The parts it has that's not original at the moment is the bag, the headlight trim, the wheels, the rubber sleeve on the hand grip, the sani emptor is a 1950s replacement as it has a sweet aire which first appeared on the 510 I believe. I am ok with that emptor. I have a tan 70s replacement hose for it that I use on it. That is what I have to say. Happy vacuuming
