I believe the photographed aircraft is a false painted "warbird". My definitive Beechcraft reference listing all Musketeer and variants production does not show any U.S. Army contract production of any Musketeer or any of its variants-Musketeer II, Custom III, Sundowner 180, Sport 150, Sport III, Musketeer Super R, Musketeer Super R III, Sierra 200. These were the popular names of all Beech production of the model 23, 24, A23A, B23, C23, A23-19, 19A, M19A, B19, A23-24, A24, A24R, B24R and C24R. None were built after 1983. Beech did build 20 Musketeer Sport models for the Fuerza Aerea Mexicana delivered in 1970. In 1972 the Canadian Armed Forces took delivery of 25 Musketeers, replacing DeHavilland DH-1 Chipmunk primary trainers.
