Jeff - I'm pretty sure that mine is the original bag. Here's the ad that was featured the other day, showing the bag that mine has. The bags that you two have look like they were from the 150 era (1936-ish), because that was when they switched to that great Art Deco lettered look. I wonder if Hoover did a newer run of those bags as the 475 moved on in the production line? Unfortunately, I cannot look at my serial number, because my 475 is in storage.....
