Mine is definitely my Kirby Model 560. I spent a lot of time restoring it. It's all original except for one upgrade I made. It has a four row brush roll (instead of the original two row).
My favorite would be the 1961 lux model 86, I love the simple lines and the red on bisquet. it could be because its my first vintage in my collection but its beautiful to me.
I'll take "over-the-top" as a compliment, thank you. The Kenmore Imperial Automatic dates from about 1935. It is more commonly referred to, in collector terms, as a "Bug-Eye Kenmore." Thanks for asking. I always enjoy showing it off.
