Its all original. How awesome. Sorry for the frustration with the belt lifter color. Haha. I'm comparing both pictures right now and for some reason I still see a black belt lifter with red script.
Congrats on a great Kirby find! I love the bag. It looks like its in pretty good shape. Most are faded and look yellow. Yours still looks gray, so you lucked out in finding a good one.
<span style="font-family: trebuchet ms,geneva; font-size: medium;">That is the original cord, and is as rare as hens' teeth so take good care of it!! You'd not be likely to find another one.</span>
<span style="font-family: trebuchet ms,geneva; font-size: medium;">Don't wind it too tightly on the cord hooks, and if I may so recommend, do not wind it in an "8" pattern. I've been told by several vac shop repair people that that is bad for cords. Also make sure not to put even a small amount of strain on either plug end. The rubber is not as soft and pliable as when it was new (keeping in mind this is a 59-year-old machine) and it will tend to crack especially at the ends.</span>
