ANH wing - THIN:
ESB wing - WAY thick (and wider, perhaps to adjust for the new thickness). Note how there's a black "frame" and that wingstars ride on TOP of this frame (which sits above the H-beam), and how inset the Kool Shade is:
Maybe the wing star's spoke's central T-bar component taper is the same between ANH ESB?
I'm not really sure the ESB wings are that much thicker. The black painted U-beam thats added seems to be the only thing that's really different. The run on both sides which adds the over all impression that the wing is thicker. The star sproket doesn't ride on top of the black beam, it's actually flush with the beam and stops at it's inside. Look carefully and you'll see it's all smoke and mirrors! The "overlap" is actually just painted which gives the apperance of the star sproket overlaping. Looks quite cheap but thats how they were made.
