This is an old Marauder Treeman, released in 1993 and sculpted by Aly & Trish Morrison. I still have a memory of seeing this advertised (or perhaps used) as Durthu, but the evidence speaks agaist that. As the saying goes 'I've had a sleep since then'. Total time taken around 7 hours, including basework. As usual, click the image for a larger view.
