Thanks for the responses electrolux137, tig21er, and kenkart. I was hoping to generate responses like yours regarding your favorites and additional information.
As for the telescoping wand of the PN-1, I thought that came later, like '69 or '70. Somewhere (probably on Vacland) I saw a RIBBED TEAL wand on a teal PN-1, so I thought that would have been '68. Just saying...
If anyone has a complete list of PNs/PN versions (Electrolux USA to present Aerus) and their orginally-matched machines...or at least might mention or post a pic of those that are missing from this thread that would be great.
I would like to get to a point of being able to match PNs, attachments, hoses, etc. with their original machines, so when I'm out and about or eBaying I have a quick reference. I personally prefer to purchase machines with their original accessories/versions.
Maybe I'll do a Hose Hall of Fame or a Floor/Rug Tool School sometime...haha!
