Franck,
I might have the answer for you? I took photos of 120086 that is part of the collection of the National Aviation Museum Canada, Ottawa, Ontario. This airframe is still in it's original factory camouflage and if you'd like, I could send you some of the images as reference?
For staters, take a look at this link. I'm not really happy with the text, but the photos should speak for themself.
