I've seen something like it in a small torch.
I usually have one or two broken sitting in an household bits drawer...
By the way, which of Brigade's? I'm not thinking of any on which this would fit.
Brill if you do!

Edit: I once thought about doing something similar with a steamer insert on a much larger model; envisioned mechanically deploying a mirror!
Edit, part deux: The 'larger model' being a Star Wars Action Fleet Desert Skiff, of which the DoY bow bares some resemblance...
