I have a vacume that was made in 1911- pat. in 1907, hand pump, original bag still in place. Curious if anyone would know what something like this might be worth? I just got back from getting someone at the antique road show to look at it- in the 10 years he said he's been doing that job he said he had never seen anything like it, took my pic with it and wanted to buy it on the spot. That has sparked my interest to find out more about it or what I can get for it. Anyone who has a clue, please let me know
