It started with the :

Diamond Jubilee in approx. 1984. That was the only model I remember having the smooth chrome top. It's easy to change that out and I think that's probably what happened with the first vac pictured in this thread.
This vacuum is known for having a faulty motor. It's beige color is rather bland.

Then came the Marquis in about 1986. This was a tanish/taupe color and lasted about a year

Then the Grand Marquis in about 1988. This was, as pictured above a white body, blue trim, blue crinkled painted top, no badge, and a smooth finish beige front. This lasted about a year and had a similar pn to the Marquis but a matching color.

Then the Legacy was very similar to the Grand Marquis.  Not sure what made it different.

Then the Ultralux as pictured above in about 1989. The body was only slightly different to the Grand Marquis. It had a badge with name and the front was a beige crinkled vynil. Also, the power nozzle cover was more rounded, eliminating all the grooves the previous cover had.

Then the Ultralux LX in about 1990, again as pictured above. And also with few canister changes. Here, compared to the Ultralux, it had the full size stick on badge, a chrome crinkled top, and the power nozzle was the first with a head lamp.

Then came the Ultralux Classic about a year later in 1991. This was the same as the LX but the colors were reversed.... and with stunning results if I may add. I bought one of these new from the dealer ( gone now) for about $600. Little did I know I was getting the last of the metal Electrolux canisters. I was just thrilled to have the last one in his inventory. I pampered that thing even despite the woven hose. I always carefully hung it over two hooks to keep it from getting worn.

Of course, not to be forgotten is the Limited Edition Commemorative model which was black and metalic. Only a few were made.

I doubt you'd find a brochure on the CE as there were only like 1000 made and they weren't intended for sale.  They were intended as a  gift. 

For some reason, Electrolux decided to make a black version as the last metal bodied vacs.  Apparently that meant something at one point. 

The ultralux Classic, or really any of the Ultralux models, LOOKED cool; but practical it was not. 

Much like any other vacuums made of metal, they were often heavy and easily dented. The end of metal bodied models was a good thing. 

Last year I gave away a really nice electrolux canister.  It was the last one I had and no one wanted to buy it.  I gave it to goodwill.  An 80 year old woman was at the donation door and she couldn't lift it. She referred to it as junk. It had a brand new hose but that means nothing to the average person.   

Did you win your CEs or buy them and how much did you pay for them?

Your profile says you've lost vacs to (3)three floods.  I'm curious what happened if you don't mind sharing?
