That's more difficult to say without knowing what unit she was assigned to, or at least the aircraft's BuNo. Her gun ports are taped, and she shows some pretty typical Corsair field weathering to the inner wing's paint, especially on the first wing panel aft of the front oil cooler facing. One would think that a training squadron closer to home would have had the resources available to keep the pain fresh and not see that sort of weathering.
It's hard to tell, but the number may have been blasted or worn off the port side front gear door. It doesn't appear to be "motion" smudge, as the rest of the aircraft is pretty clear in that part of the frame. That would be pretty consistent with an abrasive like coral dust being blown back over the inner parts of the wings and airframe. Oddly, the landing gear doors (main and tail) look somewhat lighter than the upper surfaces that is NOT consistent with the lighting and shadows. You can ESPECIALLY see it in the tailwheel doors in the front-quarter view, and if you look at the rear view and compare the bottom of the rudder to the fuselage IMMEDIATELY below it, the spaces between the white checks looks significantly lighter. It doesn't appear, however, that she's in tricolor, as she's not showing the same lightening of the fuselage sides and cowling I'd expect but because of the lighting I can't entirely rule it out.
