Thanks Tom and Tom.
Tom - Nevada: The literature I've seen always lists the tan Gs as 1967-1968; another example of a myth that turned into a fact. So the Model 1205 was launched in April 1968, correct?
Tom - Missouri: Thanks for setting the record straight about the 1955 ending of the Model XXX and beginnings of the Model E and AE, so that means that the Model T was sold as the second budget machine instead of the sole one. That was 6 months during 1956, correct?
Regarding the sale of the Model XXX adapters, I am guessing that they also made the part available for machines that had originally been equipped with the cloth bag which is why I wondered if they offered it for a longer period of time than the ones that were equipped that way at the factory. The one Charles referenced with the post of this thread has a 475 watt motor--presumably original--so it is not one of the last versions made.

Late versions of the Model XXX that I know about:
1. teal-colored bottom, chrome cover, and end cap; classic gray leatherette top (I have one of these which is stamped "12-52" on the on/off switch)
2. teal-colored bottom, hammertone cover and end cap; classic gray leatherette top (1953?)
3. gray bottom, chrome cover and end cap; LX leatherette top (1954?)
4. Disposable bag adapter (hammertone) bottom color, cover and end cap surfaces undetermined (1955)
Is this correct?

Here is a photo of the Model XXX with the LX leatherette I referenced in reply #6 (with the understanding that not all the tools are the Electrolux brand). I wonder if the gray cords (while not "Electrolux" ones) were sold with machines during the last years of the Model XXX production, because I have seen several with them along with this one and one I purchased. I also wonder when the attachments were painted in blue hammertone? Besides the dusting brush in this photo, I have seen a floor tool in hammertone; I would take for granted that there was also a carpet cleaner and an upholstery tool that were also painted in hammertone. My 1952 edition had the blue-gray bakelite small tools, the teal bakelite carpet cleaner, and the aluminum floor tool with blue-gray bumper:
