I did some research on the A5M4 whose markings I chose, and am quite sure but not positive that it was on the Hosho, a light carrier in the 3rd carrier division during the battle of Midway, June 4-7, 1942, where the Hosho played only a peripheral role. This would most likely be the last carrier combat assignment for the A5M, in contrast to what I have read before that there were no carrier based A5M's after December 7, 1941. The Shoho was also carrying A5M's when she was sunk at the battle of the Coral Sea on May7 1942.
