"Mrs. Virginia", the only airworthy P-51A (NA-99) at Planes of Fame Air Museum. Powered by an Allison V-1710-81 V-12, this model was an improvement over the P-51 (NA-91) with its V-1710-39 engine. Armament was changed from the long-barrelled 20mm Hispano to four 0.50 in Browning MGs. A contract was placed for 1,200 of which 310 were built, with 50 going to the RAF before production switched to the Merlin-powered P-51B. Under Col. Phil Cochran, the P-51A served as a fighter in 1ACG in the CBI theatre.
