Well, the information I was able to find (most of it on the Pacific Wrecks website, thanks for their hard work) was that no one kept track of which serial number airplane went with which unit tail marking when the captured airplanes were shipped back to the U.S. The tail number on this Zero was from a photo taken on Saipan but it was of another machine. When the airplane was put back into Japanese markings here in the States it looks like they took a good, but wrong, guess. Later, more research seems to have proven the markings are incorrect. Hopefully the Zero will be taken down from its hanging pose someday and the markings corrected.
