beautiful set. btw the wands were brushed aluminum, one curved, one straight.
Hoover, ever the innovator, was one of the first companies to use aluminum for wands rather than chromed steel.
Kirby has the distinction of being the first vacuum cleaner (that I know of) to have plastic wands and attachments. But when plastics of that type were first introduced to the public in the late 1940s after World War II, these new materials were considered Wonders of the Modern Age!
I have a really neat article from "Tool Engineering Magazine" from around 1952 that shows the "all-new" Kirby attachments in gray plastic, as opposed to the former dark gray (and previously black) rubberized-fiber sets. It wasn't until quite a bit later, generally the late 1950s, that plastic became equated with cheap, due to the large and sudden influx of cheap goods from overseas.
