I tried my hardest to keep the dimensions as close to the official model, so no one could cry foul in "modeling for advantage." Also, I am from the camp that believes if a ork vehicles doesn't have a face/gob, it's not Orky enough.
I must admit that the treads come from a Gundam toy, Gun-Tank to be specific. I would have used the battlewagon treads, but they are too expensive. Also, I traded for this battlewagon, so the paint job is not mine.
