Well, a Wreck Marker for one, anyway. It might not be perfectly to scale, as I was guessing what it should look like. Still, it's only part of the Deathripper (one green bar on the chassis), so it should work okay. Just about everything is painted for it, though the tusk bits need some of my version of Jack Bone.
Edit: I've now started work on the second Wreck Marker, which looks nothing like any of the 'jacks I've seen, nor does the Cygnar Warjack it died on.
