Kenmore Shown..
That is a 58,9,or 60, you could use it assembled like you see it, or take the vacuum off and use it as a regular vacuum, it was a 2 speed unit, in 60 the direct connect hose came out for the Powermate....years ahead of everyone else.,these use a 5009 bag, which is unavailable, but I have a bunch of them as I use an old Kenmore a lot, I sure would love one of these, I have several lesser models, Horizon, Vanguard ETC, but not this , the Lady Kenmore...A great vacuum at a great buy..
