I'm not too familiar with Electrolux Model Es or Auto Es, so could someone tell me if they varied in color--within the models' production years and/or for each model?  To me, the following Model E photo looks teal--not blue as the Aerus timeline states...or is it just the lighting?

Here is another Model E that looks blue to me:

 Here is electroluxkirby's (Jim's) Model Automatic E:

Thanks much for the info.  So would you say that Aerus's photo timeline of vacuum cleaner and power nozzle colors and production years is accurate?  As I gain more information from you I am thinking that the variations I have seen have either been factory rebuilts or owner renovations.  I do still wonder if there were different shades of aqua Model Gs.
