Now that's a score! My Goodwill NEVER has any vacuums and I would bet they will never have anything this good. Like Compamac said, even without the hose and PN you could still sell that for a pretty penny. Are you going to keep it?
I have wanted another 2 speed rainbow for some time. If I can find the attachments for cheap I will keep it. Otherwise I will just rebuild it and sell the shell.
