Its paintscheme looks like a blue-ish and look at background in picture. Pretty naval to me

I looked at the photo too and what i see are not palm tress but heavy equipment and what appear to be sister mustangs parked in front of hangars. While this could still be a Pacific based acft, it more likely appears to be ETO based and the paint scheme Olive Drab over gray. Unfortunately the acft serial number is not visible, but appears to have been painted around rather than re-stenciled. That might suggest the acft was silver and then painted cammo at the deployed location. Too bad the museum didn't a little more info on the picture in question.
