Most of these I've had up before but made with an old template, I've now updated them with some improvements of my own but mainly with the help of the excellent P51 template put together by Emel, FlyByShooter, Buhli and Casey1976 so big credit to them!
The P51 started serving in the Royal Swedish Airforce in 1945 and served into the fifties in the fighter and photo-recon role. The markings of these aircraft evolved over time and the easiest way to date a swedish Mustang is to check the walkaway areas on the wing which were increased with time.
