No, I own one of the earlier prototypes - untrimmed formed parts in light colored vinyl with some resin pieces (saber and dome) and no body. A fully completed pink version prototype was up for auction on eBay some months back, but I couldn't afford it. The one above, which is what I would call a near production sample ready prototype would be even more expensive.
Sure, there are things that can be improved upon the Marmit, but it is also an old sculpt and much more and better reference material is available now as well as new production procedures such as scanning and printing, yet it still surpasses the Sideshow Vaders and is still the licensed figure benchmark to strive for, for many people.
The thing that would really top everything is scanning the real helmets and armor and hard parts and then printing them in the correct scale. Though, my experience is that even those who say they want accuracy, really still prefer idealized and not the level of accuracy that the real props would give. Many are surprised by how the original pieces actually look. But for someone like me who has studied the props for such a long time... then the real accurate look is the winner every time.
