You have a great piece of history. A member of the old vacuum club brought one to a convention one year. We were all surprised how late these were made. Non-electric vacuums, while fun to show off, don't have the 'wow' factor of an electric machine of the same vintage. I know hundreds of vacuum collectors, few have any non-electric machines. The ones who do, have a far larger collection of electric cleaner. I'm telling you this because you may get the feeling these non-electric cleaners are not worth much (if you look at eBay), although many sellers are very optimistic when listing them. I've seen VERY few actually sell with a completed auction.
As you've said, you're not a collector. If you kept it, it would have a 'can you believe they used to do this' kind of humor to showing it off, but once your friends and family have seen it once, it wouldn't be something you'd use or show off again. If you sell it, at auction, please don't be surprised if it doesn't close for much. If it does sell for a good amount, that's a bonus. But don't be surprised if it doesn't sell for 'a lot'.
At the Vacuum Cleaner Museum here in St. James, Missouri - we have about 12 non-electric cleaners. They are the first thing you see on the museum tour, and we kind of laugh at them. "More work than they're worth" type of humor, before we move on to the vast numbers of electric cleaners.
