Hi Logan, I had assumed that the gray "corrugated" Lux hose was made as a replacement hose - the upright machines have a different machine-end coupler, and none of the ones I have seen have had the chrome insert. And they've all been of a flimsier material. As for the commercial machines, those hoses were much longer -- something like 10 or 11 feet long (but of the same durable material and construction). This one I'm talking about is the standard length. So to me it's a bit of a mystery. AFAIK this hose was never sold as "standard equipment" with any model of Electrolux so I am not sure about its origin.
P.S. So Sontag is still mostly farmland then? Glad to know some things haven't changed! We lived right on what was then-called Route 2. I still remember our address -- "Route 2, Rocky Mount, Virginia, 24151" (Sontag did not have an official post office so all Sontag mail addresses fell within Rocky Mount). My dad was the pastor of Beulah Baptist Church, and the parsonage where we lived was across the street.
The General Store was "up the road a-piece" from the church. I don't remember the name of the store but the man who ran it was named Mitchell. Wonder if it is still there. The "post office" there sold stamps but did not receive or deliver mail. Our mail came from the Rocky Mount post office. Whenever we wanted to mail a package we had to "go into town."
If you're ever in that neck of the woods, take your camera with you to get some photos --- of the church, parsonage, general store if it's still there, the RED dirt!! The church address is 4220 Sontag Rd, Rocky Mount, so I guess Route 2 was renamed Sontag Road at some point. btw I also still remember our phone number - 483-4151!
And a bit of interesting trivia -- it was while we lived in Sontag that zip codes were introduced. I remember that very clearly - mostly a lot of people fretting and fussing about having to learn and remember the new number codes!
