Wow, that really is a fabulous Kirby. I don't recall seeing it when it was first posted. The odd thing about it is, perfect that it is, it has a replacement cord on it. The original cord was gray with red plugs. The "male" plug has the same logo on it that's on the bag. That red cord is from the Classic-III era (1976-79).
Not to say I'd turn my nose up at it, it's just kinda strange that the cord is not original if this machine has been kept packed away all these years.
