I would like to find the brown and a green Bison.The former Bison factory is now home of E1 emergency vehicles-fire trucks and ambulances.

I got this for $18. Also, how do you find the date on it, I think mine is from 1972.

Congrats - nice piece of '60s & '70s vacuum cleaner styling—and a rare one at that!

Here's a link to the 1968 operating manual for it at Automatic Ephemera: www.automatice.org/cgi-bi...

From what I've read, there were three versions, or marks, of the green Bison: Mark I, Mark II, and Mark III; followed by the Centurion in hammertone brown and a tan bag with a brown windowpane pattern. I'm not sure if there's a code in the serial number, or if something was stamped in the casing.

I found the original 1968 patents by inventors Wilbur-Webb Selley and Richard H. Schaffer (Mark I) along with 1969—detachable handle & movable light, 1970—dirt receptacle, 1973—detachable handle with sliding member (no hardware removable necessary); which may suggest the different versions, or marks. I also found a 1982 article (below) referencing the Centurion. Apparently, the Bison factory in Ocala, Florida was shuttered in 1983; ending the company's 15-year history. Interestingly, it began as Vactronics, Inc. and changed its name to Bison Manufacturing Company in 1971 when it moved from Orlando to Ocala.

Here are the 1968 (filed)/1971 (granted) patents and other noteworthy items I located:

So when I got my Bison, I didn't know I forgot the attachments that I found at the thrift store today. I'm surprised they're still here. I will sends pics once I get home.

Bison has 10 amp motor. I wonder what the airflow is for it.

Just watched both of your videos. It's amazing the thrift store held onto that tool kit for two months! Did they just let you have it when you walked in and said you had the vacuum to go with it? You've definitely got yourself one of the true 'unicorns' of the vacuum world. I've never even seen one, except for photos here on Vacuumland.
