Gino, do you believe the dome is original and not made for production or do you believe it is not original at all? What's your basis for either?
I'll try to summarize instead of writing a novel.
A raw unfinished esb vader helmet pulled from an original mold yesterday would be indistinguishable from a raw esb vader helmet pulled in '79.
It is ONLY in the finishings that would distinguish a real film used helmet from a post production casting. And this dome and its counterpart both lacked those characteristics.
Yes I believe it to be an authentic casting, but not made for the original films. In the last several months, I've come to know of more authentic castings (non screen used) floating around out there than most people know about. I have them as well as a few others.
The only thing vadermania bases his claim on is the story given to him by the guy who sold it to him. Which always starts out the same, a guy I know who worked on the film kept it in his possession for 20 years blah blah blah and now decided to sell it off...
Anyone with access to this kind of casting and a creative backstory could put one of these up for auction as an original and most people would never know the difference. Like I said, the ONLY way to know for sure if a piece was made for the films is in the finishings.
And since this piece was obtained in a finished state, completely different than any of the originals made at that time, you cannot state with any kind of certainty that it is original.
Anyone who thinks so, I have a few originals sitting around that I could sell you. :rolleyes
