Man that's wild. The milky and caramel plastics I can see, but the green throws me off. No idea why they used that, probably just used what they had on hand at points. The entire vintage star wars line is peppered with odd variations and the like though, from castings in different colored plastics to multiple sculpt differences between the same figure. Don't even get started on paint ops. Thanks for these pics, this is very interesting. I love that wood grain effect, who would have thought you'd find that under there.
