I like all vintage Hoovers, but I would say I like the convertible series the best because I grew up with convertibles.
My parents had a model 719 when I was 2, My grandma had a U4005.
Here they are in order, a model 70, model 1010, model U4057, model U4395.
I think these pre-Convertible models deserve mention as they not only ditched the industrial brown and grey colors, but were downright hot. 64 had a warmth about it. Sorry for no photos, but I don't have these models. Have only admired them from afar.
I've admired your photos for quite some time, especially your Kirby photos, but this is about Hoover. Evidently the 64 didn't come with a tool caddy? Every photo I have ever seen of them did not include the caddy. My aunt had a 64, but she did not believe that uprights had any business having above floor tools and used only her pixie for above floor cleaning. But I digress. Thanks Fred.
Apparently - it did. Here is a publicity shot of the 64 with tools and caddy. Truly a beautiful machine and a somewhat rare one due to the transition to the "new" convertible.
That explains it. That box caddy which was used with the early convertibles also, was not very durable, so it might explain why we don't see them often. But your photo shows why the 64 is my personal favorite. The pre-convertible line went out with a bang in this model. And interesting that this line of Hoovers seemed to age better than the 65s and early convertibles that warped and did not hold their shape very well.
First choice would be the Hoover Model O! On a more practical note though, the Hoover model 541, next the Hoover Duster! I also like the 700, 150, Constilation (first models) Pixie, the (early model), Floor washer, and finally the Lark (broom vac)
My Mom's old Model 28 with all the tools. Still purrs like a kitten to this very day. But If I ever can find and buy a Hoover Model 14 Lark, I will think I had died and gone to vacuum heaven!!!!!!
