Hi Kevin
The various Electrolux attachments that you show represent several models. The three rug tools went with models XII (12), XXX (30), XX (20), and LX (60). In pic 3, the wands were standard issue from model XI (11) through one of the models after the E automatic, but the exact date I don't know. The bare floor tool was model XII through LXI, and the vaporizer is late 1960's, probably model G, or 1205. The cord I can't tell either as there is no female end, but the plug was made by the Belden cord and cable company located in Chicago at that time. Crevice tools are also late model XI, through the last of the XXX's, and the blue one is most likely XLI. As for the clip-on brush tool, I don't think that's even an Electrolux tool, as I've never seen it, unless it's part of the Model V (5), though I doubt it. The ride on tool holder was called the 'Companion,' and was introduced around 1948 for the model XXX, but redesigned for the LX, and LXI, after which, the attachments were redesigned as combination tools. And Finally, the front cover assembly was an optional kit to allow the use of the disposable bags, but not standard issue by Electrolux.
I think you would enjoy reading the posts in the thread posted by Powermate1970 'Lux 30/xxx tools.' Go to vintage archives and click on January 2013. It's a great thread and will provide you with the history you desire.
