The attachments,
the brown tools and the filter appear to go to a Black & Decker dust buster, but the filter appears to small, yet the attachment the right color for their early huge electric dust buster (What a beast it is)!
The white dusting nozzle appears eureka, but the black appears very old, with a name embossed on it?
Keep them, you'll never know when you'll run into a machine and need it (I've done it plenty of times before).
And great job on the Kirby!
