DaddyO,
If you can find some close-ups or blow-ups of shots of wing roundels (both French and RFC) you'll see that most of them are anything but perfect, and are sometimes somewhat ragged. I know, I know, this defies our logic of what it's supposed to look like, but it's the simple truth. Something hard to pull and NOT make it look like sloppy modeling.
Too bad about the clear center-section decal, I had high hopes that would be successful.
