I've been meaning to say this since I saw Phil try to shoot Thomas down on the basis that the nose bridge of the SPFX is so much wider than the GH ROTJ. At the time, Phil may have thought he won the argument.
Actually, Phil's nose bridge shows traits of modification. I know because I've done a similar mod, but I did mine correctly. Phil's work is crude here, so there strong indications of tampering. The surfaces do not flow right - and do not flow like they do on masks of verified lineage to the originals.
People should stop recommending to their costuming buddies to buy SPFX - that is perpetuating a falsehood. There's nothing sincere about the marketing of this helmet. It was made from robbing one fan in order to boost the ego and prestige of another.
