Bf 109E Instrument panel

Urban Gardini
I've got some things about this kit that I need to have answered before I can start it. Well, there's no hurry as I'm not gonna start it soon anyway but here goes. Why is it that the instructions differ so much from the alternative finish seen on the box art for the instrument panel? There's virtually no colours at all in the instructions compared to how it looks on the box. Did they change the apperance of it n' if that's the case when? Or is this colourful alternative paint scheme just an art of fiction in order to get a more attractive box art n' thus generate more selling of it? It's beautiful after all but is it correct? My second wonder is a bit different. How should I go on about it with the weatherin'? Were should I put wear n' tear on it or should it be more or less pristine?
