Jan,
Marine pilots really didn't have their own planes, and the seldom had individual markings -- including kill markings! Instead, the pilots flew pretty whatever planes were ready that day. It's true that some pilots would often fly the same plane more frequently than the others, but there was never a system where one pilot was assigned one plane. The Navy forbade individual markings on their planes too.
You'll see photos from time to time of Navy/Marine aces with "their" planes. The planes are painted up with a bunch of Japanese flags and sometimes a name. Those kind of photos are almost always staged photo-ops for propaganda. The famous photo of Pappy Boyington shows him in a plane that was painted that morning. The "Lullabelle" name was something that Pappy thought of on a whim.
So the up shot is that, you should simply get markings for either VMF-214 or 215. Finding decals may be somewhat difficult. Most of the VMF-214 decals I've seen on the web are for Boyington's propaganda photo plane. Do a Google search for "VMF-214 dedals."
To find out more about VMF-214 check out two books by Bruce Gamble:
Black Sheep: The Definitive Account of Marine Fighting Squadron 214 in World War II, and
Black Sheep One : The Life of Gregory "Pappy" Boyington. I've met Bruce on a couple of occasions and corresponded with him on more occasions. He is a good man, a careful researcher, and a great writer. I've seen both books for sale as trade paper backs at Borders for relatively cheap. They have great photos. I'm pretty sure that Bob Hanson shows up in both books as well. (I think I met him at an air show, by the way.)
I'm sorry I don't know as much about VMF-215.
Good luck!
