Sounds great - I've studied Italian, so I can ask the folks over at the Italian forums for historical reference. Just a question, though - is there a deadline on this? I'm neck-deep in university studies and work right now, so I can only skin late in the evening (when I'm already sleeping with one eye closed)?
By the way, if you have enough information about the D.520s in German flying schools, maybe I can send you a few photos for opinion - there's a great debate over here whether the camo of the Bulgarian D.520s was based off the original French colours with mottling, or German RLM repaints. :?
