Hey John,
How are you doing? Hope all is going well with your health and the remodeling.
While I'm not a huge Hoover fan, I really like the second one from the top of the stairs. Back in 1977, I used to hang out at a vacuum store in Venice FL after school. I remember the man who owned it was a Royal dealer, and also carried Hoover. One day we needed a new vacuum, and my Dad worked at the bank across the street from the store. He gave me the money to go buy a new vacuum of my choice (within the amount of money he gave me) and I chose a convertible almost exactly like the one on your stairs. It had the white metal base and yellow hood and bumpers just like yours. The only difference was the bag was a two tone yellow flowery pattern. I got it and the attachments for around $80. I took it over to the bank and put it in Dad's car trunk and couldn't wait for him to come home. I've been looking, but can't find another one like it. If I ever do, you can be sure it is coming home with me.
