Also, you guys may want to look at the canopy of the F4U-1. It is the early birdcage Corsair. The one that Whels posted is an F4U-1A with the blown canopy, similar to the one on the -1D.
Also, just a bit of historical info, the -1A in the profile is not really a Hog that Boyington flew in combat. It was just doctored up for press reasons. All of the Hogs that the 214 used did NOT have kill markings, even the ones that Boyington flew. Sorry for the nitpick.
