The Deathroller is most of the 3rd edition Deathroller but with addition of the boiler and wheels of the Empire Steam tank. The Steamtank is a full metal model, so this baby weighs a bit, but is absolutely stable on it's (unfortunately) 40mm base. On a 30mm base it would not quite be as stable.
I left the rear a bit higher to allow models to move freely underneath. With bigger models like Trolls and the like I foresee significant problems
The small bell on top of the smokestack is an accessory I found on a Lindt chocolate bunny
