nsclcctl,
I've got a couple of great cockpit photos at home that I'll post here after work or later this evening.
The Fokker D.7's interior is steel tube painted a blue-green color with a wood instrument panel. The fabric of the plane's sides is very visible from inside the cockpit. This photo shows what the plane looks like without fabric:

You can see how the fabic covering would serve as the cockpit side walls.
My plan is to get some of that Testors decal paper, scan the lozenge decal that came with my kit, make it a mirror image in Photoshop, and then apply it to the inside of the fuseulage. I'll probably lighten it a bit too.
Regards,
