To Smaster: That's a McAllister Bagless, not a Fairfax, which is a somewhat obscure machine. The dies later were sold to Fairfax after McAllister stopped making cleaners.
To Danemodsandy: That's a Lewyt Big Wheel, the first model, which was Top Of The Line, especially since it has the optional attachment carrier on the back. The Big Wheel was the first square Lewyt after the whole Filter Queen/Lewyt lawsuit was settled in Filter Queen's favor.
