I'm a bit curious, its rare for a plane with such high production numbers to not have a combat record.
"The first P-63C deliveries took place in December 1944, with the total production being 1227 aircraft. Most of these aircraft were delivered to the Soviet Union, although 114 were delivered to the Armee de l'Air."
"The P-63A-9 had 198.9 pounds of armor. It introduced the 37-mm M10 cannon in place of the earlier M4, and an increase in ammunition capacity from 30 to 58 37-mm rounds"
"Most of the P-63As that were manufactured at the Buffalo plant were immediately ferried to the Soviet Union. Upon completion, the P-63s would be rolled out of the factory and ferried from Niagra Falls to Selfride Field, Michigan. After refueling, the would be flown to Truax Field in Madison, Wisconsin where Soviet ferry pilots (usually women) would pick them up and fly them to Edmonton, Anchorage and then across the Bering Straits to the Soviet Union. The Russians used the Kingcobra primarily for close-support and ground strafing. The Kingcobra had a relatively good low-altitude performance and had the ability to absorb a lot of battle damage and still remain flying. It proved to be a potent ground attack aircraft and tank-buster, but it never received the amount of attention in the Soviet Union as did the Ilyushin Il-2 Shturmovik"

Sounds like the A model was in service with frontline units....
