This is another one of those dark painted, Erla built Bf109G-10's. In this case there seems to be only one color on the upper surfaces, the small differences more likely being the result of weathering and a slightly uneven paint application. The newly released promopicture of the coming Revell Bf109G-10 seems to show this scheme, but with the wrong enginecowling as the boxart shows it in 74/75/76.
