Some details of a painting that may help you weather a black airplane.
WW-1 Art That's not weathering!
Fokker Triplanes and early D.VII's were painted using a great big brush and a tin of olive paint. The paint was drawn over the finished surface until the brush was dry, then it was re-dipped in the paint and started again. This gives the streaky camouflage on the aircraft. Field repaints were done with thin washes of colour over the top (to keep the weight down) so the original paint often showed through. The picture above shows the streaky olive-on-natural-linen camouflage showing through the overpainted black.
Now, Jacob's D.VII, No 365/18, was from the early batch with streaky camouflage on the fuselage so it's fine. The wings would have been lozenge fabric no matter what the fuselage. There is a suggestion that they were initially left unpainted, before the whole aircraft was painted black.
The fact that I know this stuff may qualify me as a nerd.
