As I understand it, each photo, if taken in France, will have 2 numbers - an AEF Number, which was applied to the negative in France, usually in the lower left hand corner, and an ID Number, which is assigned by the SG once received in the states. This photo has 3 ID Numbers and 2 AEF numbers. They are all the exact same photo. Since one appears without an AEF Number, it could be a photo taken here in the states, and for whatever reason, assigned an AEF number at a later date, or in this case, two differing AEF Numbers. Why assign two AEF Numbers to the same photo? However, for there to be 2 different AEF Numbers, there had to be a negative that had no AEF Number. Certainly appears to be a big flag that this could have been a stateside photo.
