To support my Queen's Own Arc Rifles (which I haven't finished painting yet), I have made some transport and guns. Not sure exactly what stats I'll be using, yet. I have done 4 steam tractors, a couple of arc cannons, and a Tesla-style arc generator.
The barrels of the tractors are from model railway fuel tanks and the wheels are from toy tractors. The rest of it is built from scratch.
In honour of Colonel O'Truth, http://colonelotruth.blogspot.co.uk/, the rivet count is 331.
