I got this Penitent Engine for half price, before I knew much about the Witch Hunters. It seems to be pretty poor in game terms, but I just love the model!
The paint job is quick and dirty Chainmail drybrushing on most of the model, but the "pilot" and scrolls have gotten some attention. I tried a "dirty flame"-look for the flamer on the left of the image, but I don't feel quite satisfied with it. I might get back to it in the future, but for now it's into the display cabinet for this model.
