The fifth leading Imperial Japanese Navy ace was Takeo Okumura with 54 victories. The model represents WI-108, an A6M3 Type 22 assigned to the 201 Kokutai at Buin in September 1943. The only profile I was able to locate of this aircraft was in Osprey Aces 22, IJN Aces 1937-45, which was depicted in a badly chipped paint job. Most photographs of operational Zeros show little or no chipping, so mine is rendered similarly. Okumura was credited with four Chinese aircraft prior to the start of the Pacific War. He was assigned to the aircraft carrier Ryujo during the Guadalcanal Campaign and was transferred to the Tainan Air Group at Rabaul. When operating from Buin in September 1943, he was credited with nine victories and one shared over five sorties, a record for the Pacific War. He was lost at the end of the month attacking a convoy off Cape Cretin, New Guinea.
