Howdy,
Figured I may as well register here. As I mentioned in the RPF thread, I discovered the part in a bin over @ Apex yesterday. I have a Fett Helmet in my garage that I need to dig out and compare. But, as it seems to turn out with me, I probably have a casting of a recast off of a recast - so I don't know if I can trust the sizing. Is there a reference here that shows the rear of the helmet with a ruler on it? That would end the speculation real quick.
As for going out to Apex again, good luck finding another. Good luck finding a second of ANYTHING in that place. It was literally laying on top of some parts in a bin inside the place (not in the yard). It will be like finding a needle in a haystack.
Let's figure out if it is the real thing first......
