I wish I could share such a thing, but I cannot share that kind of data publicly (or even privately).
I can tell you that this finish is consistent with the filming prop. There are a number of other features no other Obi saber has ever properly replicated that are present on this hilt, and to the extent I could demonstrate that with photos next to the stunt saber, I have done so. Unfortunately, I cannot share hi-res photos of the hero prop. All I can give you is my word that this saber does represent the closest thing I can offer in terms of accuracy to the original prop.
So if you want to take me at my word, I'd say order it with the finish as it currently is. If you just want something shiny, I can do that for you too. It just wouldn't be accurate. I can tell you that the one in my personal case, Serial Number 001, has the same finish as what everyone else in this thread has posted. Nick Cline's images accentuate the sanding step more than you would see it in person under normal lighting, but the general idea is correct.
