The white, or ivory-colored, PN-1 with the teal bumper and plastic wand (there was also one with a brown bumper to complement the tan Model G) was made for the following cylinders:
1) Model R - 1960-63
2) Model G (aqua) - 1960-66
3) Model L (ivory) - 1963-66
The first ones had sans-serif "Electrolux" capitals on the hood--they would have been the ones with the smaller bearings. These also had a gray cord and no clean-out port on the bottom plate. Circa 1962 the "Electrolux" caps were the more famiiar serif style and the words "Power Nozzle" were added underneath in a sans-serif, smaller size. The cords on those were aqua, and the bottom plate had a clean-out port. Any of these that you might see with a detachable wand have been refurbished. Since most of the wands of the pns with the brown bumper have been replaced with the detachable ones, they were the ones that had a cheaper plastic--but I think it still had a metal tube underneath. I have one that is cracked at both ends (it's in a storage unit), but the wands on the pns with the teal bumpers are typically fine.
The commercial version used for the canister models C-A (1962-65) and CB (aqua, 1965-66) had a detachable one piece steel wand without a sheath. In addition, the cord had a grounded plug. Jimmy/"Rugsucker" and Tom/"dysonman1" have them for their Model C-As--maybe one will post a photo if they read this. I am hoping to purchase one for my aqua Model CB, but they seem to be rarer than a MN snow in August.
