I am trying to remember a specific Elux. It was designed like the model RC but had a permanent molded black cord like the "S" had, but it had a cord halo and looked exactly like the RC. It had no power nozel outlet. It was the colors of the AF. Does anyone remember this little Lux?
I am not familiar with a Model RC. The only three vintage Electroluxes I am aware of with permanent cords were Models E, T and S.
The only model (I know of) that had the colors of the Model F was the Model R. It came standard with a halo but an optional cord winder was available. Its cord is detachable, and it has a power nozzle outlet. See link. You sure this isn't what you're talking about?
