The plane is painted as it looked in 1965, while serving with ESK 726 at Aalborg Air Base. The SM/67 paint was introduced in 1967, though it took some years before every plane had been repainted, as you can see in this picture. The plane in front is in the old paint scheme, while two of the planes behind it, had been repainted
