Incorrect HarryC. The slats were fully operational on the soft wing.
The outer panel, which is what he is showing in his pic in the op, had fixed slats.
The outer slats aren't fixed. They are hinged at the leading edge and rotate around the hinge line, with the effect that the leading edge of the flap moves up and down. They do not slide front to back as other slats, but rather rotate around the axis of the hinge line.Here is a better shot showing the hinges at the front.
