The original Memphis Belle, for many years, was displayed on a specially built platform in front of the TN National Guard Armory on Union Avenue in Memphis, TN. I was born in Memphis and the house in which my family lived was about two blocks away and I remember seeing it often.
The plane was moved to the TN Air Guard hangers at the airport in Memphis for "restoration" in the late 70's and I was able to take a look that it and another B-17G that had just been painted at the Boeing plant. That aircraft was on its way to a museum in Florida. The crew members of the Memphis Belle had scratched their names in the vertical stabilizer and they were, at that time, still legible.
The Memphis Belle was finally moved to a specially built facility/museum on Mud Island in downtown Memphis. The plane sat there for years and was on marginally protected from the weather. The USAF, which still had "ownership" of the craft, advised the city of Memphis to either take better care of the plane or that it would take possession.
Either the city agreed or the Air Force exercised its rights and the Memphis Belle was moved to Dayton, OH for a real restoration. It is supposed to be put on display in the near future but, it is, IMO, where it needs to be for everyone to see and appreciate its history.
