Re Fairfax..
I used to think it was a early fairfax,,,and it DOES look like one, but it is different tooling, the McAllister is smaller in diameter and of course the attachments are nothing at all similar..The McAllister is a great machine, I have the hose ,wands and dusting brush, Clay Floyd had the attachments and I think they are in the museum at Tacony, the rug tool is really special, big and ugly, but it really cleanes great!
