Are there any Filter Queen experts who can help me figure out the model my Grandmother had in the 1950s? When she moved to their new home west of Indianapolis in 1952, she bought a new Filter Queen to keep the place as good as new. I remember it vividly: the colors were not those that I see on the model 31 pictures. Hers was pretty much brown all over. Certainly no power tools. There was some type fabric cloth with pockets that could be hung around the top of the machine to carry attachments. I think you could pull the motor unit off the ring that held the wheels. She stored everything in the original box that was pretty enormous Any ideas?
