Hi Guys! Well, the story is quite simple. My Great-Grandmother and Grandfather purchased the model 31 new. It's been around as long as I can remember and I always knew where it was kept. So, from the time I could walk I would go get it and play with it for hours whenever we would visit. To this day, when I look at the vac I can still hear my Great-Grandmother, who everyone called Ma-Ma, laughing at me when I was small struggling to pull the Filter Queen around. Many years later, when the old FQ had been put into storage because Ma-Ma could no longer handle it, her last daughter got married and they were doing some remodeling on the old house. They were cleaning out and throwing away things as you often do during those things, and they were going to throw the old FQ away, but she put her foot down and said NO, that I had pulled that vac around since I could walk and that I would get it. She called me, I went and got it, and the rest, as they say, is history. Toby G.
