Hi Otter!
I’m sorry but your drawing is really not correct at that point!
Have a look here: http://109lair.hobbyvista.com/walkar...943/POF048.jpg
The pic shows the front of Yellow 13. That’s a G-10/U4 and not a Buchon.
Another G-10 nose: http://109lair.hobbyvista.com/walkar...610824rg-2.jpg

Your pic shows a G-6 (ex trop-Version). There the oil filler cap was situated lower.
The profile will be printed about 25cm wide. So these details will not get lost. I don’t mind if the rivets are not 100% correct, but the main things should be okay. Hope to finish the wing today evening!
Cheers, Simon
