The model is one large resin casting (complete with all four wheels and the spare) plus white metal castings for the two man crew, steering wheel and folded down canopy.
The model is notably smaller than the Warlord Games one (bottom).
I undercoated it with Citadel Chaos Black spray, followed up with Citadel Zandri Dust. The tyres were painted with Vallejo Black Grey. The spade blade is Vallejo Black, the handle Citadel Mournfang Brown.
