One can see that brown plastic has been used in the creation on of the figure, or that it has been professionally painted/ dyed on in the factories during production (I do not know how these figures were/are created), and that it isn't one of the white hooded versions that someone painted brown over the hood! It would have become evident by the age of the figure and the white would have shown through.
This div probably sat there one day and thought to himself "right how can I make some money".. then proceeded to his garden shed to paint a vintage figure and pass it off as a one of a kind ultra rare variant.
