The first roundie I ever saw was at a garage sale, it was a low end metal cabinet one. The round screen was insane - I had only seen rectangular ones. CTC-38s used to pop up in the trash all the time back then (last tube RCA color set I saw in the trash was about 5 years ago, but was a newer rectuangualar console andwouldn't fit on the back of my Harley
)
For whatever reason, I saw very few tube TVs of any type being tossed when I was young. Oh well..
