OK, on your top map is the actual UV co-ordinates. Everything outside of those lines doesn't appear on your model. So you can go over the lines, as they have done in #1, but a neater way to work is the way I did it. You work with the black and white one, import it into your graphics application. Then apply a white colour mask, invert the colour mask, and remove holes. The area left will then be the areas you texture. Picture for the top section (the curved piece), metal for the small round bit on the bottom right, and then either wood, plastic or black for the "spokes" of the fan.
