Nice! That was the floor tool that originally came with my HVC200, I hope I'll find one someday.
Sorry to disappoint, but that exact machine wasn't made in 1980, although it has a black switch (which was only on early-ish numatics). The eyes have black outlines around them, which came around 1987, and the hose is a newer one from around that time too, but these could have just been replaced over time, so I could be wrong. How did you figure it was from 1980?
