Hi Kevin.
Unfortunately, I don't have pictures of these tools, that's why I sent you to the thread started by powermate1970. If you haven't looked at the entire thread, you should, because it has all kinds of pictures, as well as beautiful machines.
Yes the patents are in the correct order of production, and I will post other tools and accessories later tonight.
When Electrolux opened it's factory in Old Greenwich, Connecticut in 1933, there was a skeleton crew that came to America from Sweden (where Electrolux was founded) and helped start the new company. One of the key people was Gustaf E. Lofgren. And while I don't know a lot about him, he was the man who designed the tools. Gustaf, and his engineers perfected the basic tools out of polished aluminum, and the only changes wer the rubber trim matched the leatherette of the XII, XXX and so on. The big changes came around 1955, with the introduction of the model E, and that ushered in the various colors to the combination tools.
And speaking of changes, it was 1948 when Electrolux introduced a whole line of attachments and devices like the Cord winder, Companion, Polisher, and Garment Aire bag, as well as special tools like the white bristle wall brush, and white bristle dusting brush. In this case, only the brushes changed. Sometime after the introduction of the E automatic, tools acquired the plastic shell. My history stops with the last of the LX's, and either Charles Richard Lester or Tom Gasko (perhaps both) should respond to that as they are far more knowledgeable.
Pictured here is the basic bare floor brush that went with the model XII (rubber trim was milk chocolate brown), and the tool stayed in production to the last of the LXI's.
