Tom,
I just started using this site & though it has been ten years, this is a very impressive story. Shame you couldn't save more. My parents had what I think was a 652 which I enjoyed using when I was a little boy. My father taught me how to remove the hood and change the light bulb and how to replace the belt. I currently have a 1060 which serves as my go to vacuum. it is missing its lens so if you or anyone else has one to spare, I would be very grateful.
Charlie
