LEGO Star Wars Sandcrawler 10144 complete set, however it does not come with the instructions booklet or box. Note that some of the pieces are dusty so it could do with a light clean. Also one of the 3x1 reddish brown slope pieces (part No. 4286) has chipped as it was brittle. I can send pictures if you want to see. If you use BrickLink you can pick one of these up for a couple pence.
