When I look at the second pic (attachment 468804 above) I can convince myself I do. Again, almost a highlight.
I know when collecting old action figures, like GI Joes, that any with a metallic paint job are a hassle to find with the metallic parts in pristine condition. So you'll have, say, a vintage hooded Cobra Commander, and the gold paint on his belts will have worn away although otherwise he seems to be in great shape. So like I've said, the theory I'm going with is that the windvane had a black undercoat, but was given the bronze/brass color over top--not an uncommon technique. But the crappy metallic paint wore away SUPER easy, leaving only faint hints, traces, and highlights. Might also explain why the black on the windvane is less patchy than the emitter and booster. In addition to being protected from wear by being narrower--less contact with other objects because wider sections hit things first--it had another paint layer.
This is TOTAL speculation. But I see bronze in ANH and ESB. And a repaint between ESB and ROTJ makes little sense given the paint's condition. So I've constructed a narrative that makes logical sense to me. It's not evidence, but in the absence of better pics, it seems like an ok way to proceed.
