I recently acquired a machine from the Ukraine (which arrived in a potato bag - seriously) that only deepens the mystery.
It's a virtual copy of the McAllister Bagless as well as the ConVac. The McAllister came out soon after World War II was over, and a design patent was obtained in 1950. The machine had a cloth filter between the motor and the pan, making it 'bagless'. It's a filthy mess to empty. According to a magazine article from around 1948 about the "post war" models, this was described as being a wet vac as well. No grounding pin of course, and a flow-thru motor. Talk about shocking.
