This is an International Harvester model H 542-11, military designation M 426, a WWII 5-ton hauler that saw a lot of civilian use after the war. I did 2 civilian cabs as well as an extended 3 axle frame, as the vehicle had several common military and commercial variations and customizations. It is done for S scale (1/64th), so the 2 axle frame is 80mm, the tandem axle is about 100mm ~4 inches. The client sells this as assembled and painted model. Here is a link to the initial ZBrush part designs. The 3D prototype prints- the metal castings, and the assembled and painted models are linked in the top paragraph.
