Hi Nick-P
Actually the Electrolux floor brush is very common. Looking at the rubber trim I place it at the end of the run for the model XXX (December 1937 to October 1952).
This tool was first designed about 1933 by Gustaf E. Lofgren for the model X11 (12) and was standard till the model E replaced it around 1954/55 with the combination rug/floor tool.
As for the wands, they look like the steel wands also common with the X11, XXX, XX, LX/LXI, and E. It wasn't till the later models like the AF, or the G, that aluminum wands were introduced. Certainly by the time the 1205 was being sold.
Most of us have at least the basic Electrolux tools in our collections. They are a dime a dozen!
