It looks nothing like either of my sets of Jedi moulds. The traps are significantly smaller on this helmet, were talking cm's. I agree that cap is hardly reliable as a source of information. Unlikely either party can prove their position without going back in time.
Edit:
I am not interested in dissing anyone, especially TE. My point is that my moulds of the background helmet are different to my newer moulds from the unfinished helmet, and these are totally different from the new TE ROTJ helmet. I am interested in how many moulds were used for the Jedi helmets.
What would make more sense is whoever moulded Matt's Jedi helmet, created a huge amount of shrinkage when copying it, which would account for the difference in the traps.
I would like to see Gino's Jedi moulds too, but this is doubtful!
