Lyric1 found me some profiles and photos of this Wildcat scheme. It is an F4F-3P, which was the armed photo reconnaissance version of the Wildcat. The rear fuselage tank was removed and replaced with a camera but otherwise it was much the same as the fighter version. This aircraft flew with VMO-251 based on Guadalcanal in 1942.
This squadron often used fake gun patches to give the impression of a heavier than in reality armament. So although the real aircraft had four guns I've added a couple of extra patches on the outboard guns.
