That was the model used in "I Love Lucy" as the "handy dandy' vacuum cleaner. I have that same model with all attachments and a ton of disposable bags.
I have seen a number of that model on eBay within the last several years, with high starting prices (they didn't ultimately sell). Perhaps because of the "I Love Lucy" part, sellers think buyers will pay greatly for it. I can't tell you it's 'value' as a dollar amount because I've seen many of those not sell on eBay.
