Hi,
I for the life of me, cannot find out what this part is or how it was used/attached to a vintage Kirby vac.
It opens, has a glass window on one side, and the logo on the other. It looks like a hose attaches to it, so thought it was a dirt receptacle, but it's small for that.
Any help will be greatly appreciated!
Thanks!
