It's a lovely model but it is STAR WARS screen accurate and the dimensions don't match the cockpit of the ESB & ROTJ one.
Now spot the difference in the ESB and ROTJ cockpit from this model
The dimensions are different. The frame is higher. Now weather this is an un-cropped cockpit view it is on 2004 bonus disc. But I think it is a slightly different angle to the cockpit shot I am pointing to.
You going to have to drop the Star wars cockpit I already have said we would not see the mandible in the first film because we never get to the camera angle as the one in question.
You also need to think about what happens the higher you go with the camera the mandible becomes more visible. And think of it like the cockpit got bigger and wider to the right. It's a bit of a Tardis effect.
The cockpit shot from the 2004 Bonus disc is an un-cropped version of the cockpit view I can confirm that now.. And that means we are lower in the cockpit than I initially thought. But it is slightly less wide.
I am happy to reconcile and conceed that the madible would not be visible at this angle based on filling in the blanks at what angle the camera is now positioned at. Now we can see a better picture of where we are in the cockpit. :) 3 down 1 to go...
The Space Slug escape POV View still needs to be explored also.
This is absolutely in no way a cropped cockpit... well it might be, but It is much higher up and looking up and I am pretty much certain the conditions here are a dead cert for seeing the mandible here.
It may be worth trying to match up the angles with that full cockpit to ascertain position of the camera. The question is if it is cropped then it would be more than likely cropped at the bottom and not at the top as the 2004 bonus disc displays.
