Star Wars Ewok Village 99% complete

Original 1983 84 vintage in Fairly good condition with most of the original parts. As far as I know the only thing missing is the net that goes underneath, and it needs some replacement black string for the elevator and Boulder. There is no breakage. But for some reason there is some unfortunate discoloration with some of the brown Parts which are turning green in much the same way that the Chewbacca action figures limbs will sometimes turn green. It is an aging and sunlight discoloration issue. I got this in a larger collection and the original owner swore to me that it had never been in direct sunlight but I have my doubts. Aside from the discoloration issue it''s really in very nice shape.
