Id have to say the Electrolux Hospital Model G,,in Bronze and white, with matching PN, and tools. (Altho ive never owned or used one, have only dreamed if it)
And, im extremely fond of the 1975 Electrolux Golden Jubilee,with the blue 50th anniversary sticker on the back of the machine, and top of the PN. Its one of my childhood vacs (Grandma bought one new in April of 1976),,has a very special place in my heart.
