It's a kENMORE.....
That is a Kenmore clone, as Birtman Electric; known for their BeeVac house brand, also made most uprights for Sears as well until the advent of the twin-fan Singer built upright machines sometime around 1960 or so.
They were kinda good. I had a Kenmore from about 1948-49 once...two toned brown. I could never figure out it's electrical gremlins tho...it always seemed to zap me every now and then. I've heard...thru yarns spinning that this was a fairly common Kenmore/BeeVac issue.
However I have an earlier one that Jeff Parker and I found many years ago at the ALSIP fleamarket in Ill. and it never zapped me and worked quite well.
So who knows....
