Tyler,
Where have you found the black bellows and fill tube? I really only need the fill tube for a Convertible I have as it has the original rounded slide-in bag holder, not the later style push on style holder. I very rarely use the Hoover and its mainly because I have to cut the collar of any bag I use so that it will fit into the holder and there is always a ton of dust that leaks through. The fill tube and bellows in my machine are also white but I'm not to concerned with the color if it would mean that I could use the machine a few more times a year than I do now.
