I noticed something I had not seen before, or perhaps there are some
modifications to this plane.

Is there something different about the wingtips? An extension in front of
the normal edge? It looks like a cuff, or a change to the washout.

Is there something different about the windshield area? It looks like it
has more angle, and is more streamlined, and perhaps a one piece windshield
instead of a normal segmented windshield.

Anyone?
