Have a look under the chin/mictip areas.. no cap is pushed n/warped like that. Its a ROTJ feature. Its the same on the first TE ROTJ, as it should be, because its from the FIRST TE ROTJ.
I own one of the ealier models, and its no spring chicken. It is quite apparent the new one comes from it. The same problems have carried over to the new version. The only difference is; is that the new face has been sharpened. Which IMO makes it look more correct, to how it actually was (save for the chin/vocoder which now looks too sharp).
Anyway, the orginal TE ROTJ helmet had its moulding issues all the same, and they have come through on this one aswell.
And as for the back cap, its from a TE ROT aswell. Same strange profile shape as the old version... sit it next to a cap/or TE ANH and its completely different in its curvature.
Thats about the most basic way of saying... ITS NOT FROM A CAP.
Although I'm sure there will be those that will believe him regardless
