You know, the more I look at the photo, the more you are right (not that you should be wrong or anything, I was just going by an interview I have). The Hellcat in that pic has the windows behind the cockpit that were only on the very first production F6F-5's, of which Minsi III was one. The pic that I have of his plane back in the states doesn't have a name on it, but it does have all 34 kills. Also, the kills on this plane were under the windscreen and not the canopy, unlike the pic above.
Oh well, I was mistaken, not the first time nor the last...
