That was a STEAL at that price; the filter unit that was used in home demos is worth that price alone!
Great score on the attachments as well, especially the Handi Butler set and jigsaw.
That grey plastic fan is a lexan or nylon composite that is notorious for deteriorating through age and stress cracks developing whether it is used or not. If the cracks are there, then it could grenade at any time when it is running, scaring the crap out of you if it happens.
I would replace it with the newer cream-colored amodal plastic fan before using it for regular service.
This would be a good time to do a complete restoration on it, as well!
Below is a link to the resto of my Tradition; hopefully it can help you with yours if you go that route....
