I don't know if I can give you as specific an answer as you are looking for, but here is some helpful information. The Norca was considered a separate brand from the Hoover, and sold by non-Hoover dealers. I'm not exactly clear who these would have been. Essentially the Norca Model 1 was a Hoover Model 300, but with a 4-brush agitatior without Hoover's biggest selling point, their patented metal beater bar. The successor to the Model 1 was the Model 80. It was just like the Model 305 (successor to the Model 300) again with the agitator without beater bars. I believe there was also a Norca hand vac around the same time. I believe it was no different from the Hoover, just a different name and dealer network. In later years Hoover used the Norca name on a line of replacement bags and accessories for use with competitive brand vacuum cleaners.
