Ok I been searching Google high and low for past images of the Ju88 cockpit. And it would appear most of the frame issued mentioned above have been there for a long, long time and I have even incorrectly labelled the pilots sliding widow handle as a fault “duh”, I will have to edit my original image above to reflect these findings, yet can not access Photobucket during business hours ( can't even see my own images

).
That said the tear/holes in the front pillar of the sliding widow seems not to be evident in anything that I have found thus far and is something I just can not recall ever seeing in the past. I guess once I noticed the tear which is now quite distracting my mind starting inventing other problems.
For reference here are the original Ubi pages Ju88 implementation images and as you can see the previously high-lighted pillar seems to have no tears or holes in evidence.
Also, and sorry, but come to think of it, maybe this post should be in the 6DOF debugging thread instead? If so I raise it there instead.
