Electrolux Corporation - Models 1401-B, 1453, 1521, CB2000
Just located the Model 1453 patent. I had no idea that it was launched in 1981; I had always thought it was around the time of the Olympia One's debut. That may indicate that the Model L was marketed until that time, or that Electrolux had ended the budget model option for a time and then reinstated it.
Due to the upload limit, I've posted only a few representative images of the CB2000.
The wands, a separate patent, were likely used for both household and commercial cleaners.
I was unable to locate a patent for the L-shaped power nozzle itself.
Photos (note - at that time only the years the patents were granted were included on the image pages; production likely began during the filing years shown on the details pages included):
1-3. Olympia One model 1401-B (and Silverado Deluxe 1505)
4-6. Deluxe Special Model 1453 & cord winder
7-11. Model 1521 (Diamond Jubilee, Marquise, Grand Marquise, Legacy, Ultralux, Ultralux LX, Ultralux Classic)
12-16. Model CB 2000
17-19. Wand
20. Self-Cleaning Joint (elbow for PN5, PN6, PN7)
