How about the fuselage sides being misted with RLM 81 over a 76 base?
Cowling and gun trough could both be late Dunkelgrun, or one of the crossover mixes with RLM 74?
Nose front and top of cowl in 75?
Rudder in a different mix of 76? (different production house/line?)
What do you think about the wheel hubs?
