Thanks Guys
Hers looked very much like the 350 that dysonman pictures. The box was different, but that's a minor detail. If I find that model sometime, I might get it in her honor. When she passed and my grandfather had to fend for himself, he traded it in for a Hoover convertible, and things were never the same. That 350 was one very cool machine and I played with it for hours, but I remember having to get someone older sometimes to press through the rubber hose end to depress the release button of the wands and some tools. I rank it right up there with Kirby and Electrolux.
