I think this model came out in mid nineties, and it has been in my collection for at least twenty years. This model is old. It is so old that the tracks still have road wheels hidden away out of sight. Somehow after all these years, this old AFV called to me. In this third incarnation the tank is painted to match my DKoK force. At least that is what I had intended. I should have looked at my DKoK before painting, as I exaggerated the modulation a bit much here. But no matter that, I'm happy this old mortar tractor is back in business. It can now sit on my shelf. Again.
Since I don't play 40k these days, but plan to do so when the new edition drops, does this model even exist in current 40k? If there is at least an existing model there might be some hope of there being rules for it. If I can't find rules, I can always pop the mortar out, and use the vehicle as an open topped Ogryn transport or something.
