Hey, I know you told me that I can post here for plane history and so we could learn about history. Now, that you was saying about How many Vought F4U-4 Corsair kills before World War 2 ended. Here's the answer(i think) that -4 which it has less 50 kills like you said I think. Anyway, Capt. Ken Walsh of VMF-222 and his F4U-4 'No 13' BuNo 80879 with 21st kills on June 22, 1945(dont have a picture of him on F4U-4 but looking for it, but on that day was his last kills over okinawa i believe).
