Does anyone know

the years that Kirby manufactured this replacement bag in gray and red. I'd only seen the one in brown until I came across this one in gray.

The tag on the back says 1981, so I'm assuming that was the year it was made. However, I'm just curious about how many years the gray bag was actually made and what that range of years would be. Thanks!

Kirby 518 (1958)

I think that it may be for Kirby model 518

That bag would look smart on any 500 series Kirby with red, gray, or even black trim IMHO. Kirby has had many replacement type bags over the years, each one a little different.
