Keeper!
Hey Chris, that's really a nice machine. I would keep the original bag for posterity, and purchase the newer style odor-fighting disposable bags from Oreck. They are a cloth type bag similar to hepa, and have an odor fighting charcoal liner. The filtration is much better than the paper bags, and the airflow stays 20 percent stronger as the bag fills. They are a little pricey to buy a pkg. of 8, but if you're not going to use this as a daily driver and just want to try the premium bags, I'd be happy to send you a couple for just the shipping charge. I work part-time for Oreck and these models if maintained can still be good vacuums. I know Orecks get a lot of flack on this forum, but for what they are, they do a great job. Congrats on your find.
Rick
