I'm sure the one Dave pictured has had the chromate dip treatment. This is common in later SERVICE pullies but was not done on original pullies from the C2 or early C3 era.
It's easy to remove if one so-wishes, though. A short dip in a slightly acidic solution will do it. Not too long or too acidic or the base zinc plating will go, too.
