Cordmatic. They also produced cord reels for the earlier luxes (meaning the XXX, and LX, LXI), as well as the first Hoover Portable with cord reel, before Hoover began to make them in house.

My recommendation, is to just find a real nasty beat up Cordaway, one that is non all original, besides the cord, and as you probably know, the cord reel is a one piece setup, with two set screws. Just then switch the complete cord reel.

Or find a beat up Eureka canister with the appropriate cord, then pry off the black cord reel cover (the one that has the round copper connections), and just insert the new leads, and either sodder, or do what you have to, and rest the black cover. Make certain the leads are not touching eatchother, everything is clean, and re wind the cord in the original direction, and retighten reel.... 

I hope this gives you some direction. Good luck! A little understanding and practice goes a long way with things like cord reels. No need to be afraid, just use common sense, and have courage...
