Yes, this site is a great venue for gaining knowledge, I'm not denying that at all.
Based on your age displayed in your profile, I had assumed that you would recognize a Concept One bag, as I would again assume that you remember them being in the stores being sold new.
Also, having seen your posts in this thread and this thread that both have to do with Hoover Concepts - even containing photos of machines that use the bag you're selling, again, I assumed you were either calling it a Kirby part in a 'tongue and cheek' way, or in a way that would bring people into the thread to call your bluff, and provide all of the information you needed.
You also seem to have a pretty good working knowledge of Hoover items; I guess I never noticed it was limited to canister machines.
Clearly my assumptions were wrong, and I apologize for my statements - hyperbolic, accusatory, or otherwise.
