And that is an F4F-4 pitot tube. The -3's pitot tube was a straight spear type out of the leading edge of the left wing, about half way between the outboard gun and the wing tip . . . that would be the outboard gun of the two guns in the -3's wing. On the other hand, though, you were careful to pick up on LAG use of nine stripes on the rudder vice the regulation thirteen . . . unfortunately, if that's a VF-3 insignia below the windscreen, and I think it is, VF-3 was a SAG squadron and used the regulation thirteen stripes. The LAG squadron, VF-2, did not sport a squadron insignia in the non-spec blue-grey camouflage.
