Late AF PN
The Elux Model AF, in 1959, was offered with an optional power nozzle, as it had a power nozzle outlet on the top center of the machine, to the left of the chrome trim.
The first Elux PN-1 was white with beige trim. It was only sold for one year as a distinct accessory for the AF until the Model G was introduced in 1960, when the PN came out in white with turquoise trim.
Incidentally, the white/aqua PN from 1960 matched the early Model G and Model L (from '63), and the Model L from 1968.
The earliest Elux PN-1 from 1959 only matched the AF and R for one year. It was the first year that Elux offered a PN...in fact, it was the first year ANY canister vacuum was offered with a power nozzle.
