Hi, mate, I've never seen such degree of detail, even in Deutscheluftwaffe. I guess that your best choice is try to scale the whole device taking 79,4 millimetres as reference, or 89 mm (diameter for the holes). With that and a couple of pics you can end up with a good result. Cheers and good luck!
It's true, I didn't realize that in the model everything comes toghether but in the real thing it doesn't move, is part of the wing. Now I am convinced that it must be cutted off and corrected.
Thanks a lot for your help!
