Bison:
Hi jill1990:
The Bison was made in Ocala, Florida, and was indeed a spin-off of the Kirby, though I only know that it was designed by a group of Kirby salesmen disatisfied with the company who decided to build a better mousetrap. (And the Bison wasn't it!) I've only seen and used one, and that was at one of the conventions of the Vacuum Cleaner Collector's Club. Personally, I was not fond of it, and for me it was indeed heavy and akward, but I'm no judge of the machine good, bad, or otherwise. I'll say this, I don't want one!
As for still being made? no Bison went out of business many years ago, in the late 1970's I believe, though it could have been in th 60's, again, I'm not sure, but in my opinion it was a beast!
