This is the gear box of an old Dutch water mill. Well, nearly Dutch. It is all wood, and still working fine:
Olympus XZ-1, 28mm, ISO100, f1.8, 1/8s
It sits inside this water mill (third contest entry):
Olympus XZ-1, 35mm, ISO100, f1.8, 1/2s
This water mill is called Haarmolen in Dutch and Haarmühle in German. It actually sits just across the border in Germany, so I suppose it isn't really Dutch, but we will fix that when we invade.
