Up to this point haven't tried the extra step of dry brushing over a wash.
For shading and highlighting, the combination is the easiest technique, IMHO. In this case, though, it was a wash intended to represent ingrained dirt, which is why I drybrushed over the top of it with the same paint as I used to make the wash. I wasn't sure it was going to work, but it also didn't feel like it wasn't, so I just gave it a try

Weathering, if you ask me, is something you can't
really screw up because if the effect doesn't come out the way you intended, you can always just go over it again with a new attempt. Usually, this will add to the depth and realism of the weathering, even if you didn't start out with that in mind
it's always interesting to see you work with the added criteria of historical accuracy!
Good to read someone finds it interesting
Every time I see it used that way, I can't help but see a bullseye!
Have you seen
Top Secret?
Unfortunately, there doesn't seem to be a clip online of the scene I mean, so we'll have to make do with this:
In case you haven't seen it, when the minor characters are waiting for the main ones to board the aircraft, Deja Vu and Chocolate Mousse are throwing darts at the roundel on the plane
Why not put those few links on the top behind the skirt?
I had already split and re-joined the track at the top, and I didn't want to do that again because of the difficulty of getting it back together. I agree that it would have been the better place otherwise, as I could have painted them more simply because they're largely out of sight. The lesson from this for next time is to be more careful to work out the number of links needed
