I bought these from a fellow club member, they are resin castings from Britannia Miniatures/Grubby Tanks.
I painted these in a light grey undercoat, followed by Iraqi Sand with NATO black splodges and gun barrel. Tracks are German Grey dry brushed oily steel. Petrol cans and helmets are Tamiya NATO green. Canvas covers are khaki or German Camo Beige. Exhaust is orange brown and vision blocks are Azure. Faces and hands are flat flesh, goggles are English Uniform, with NATO black and oily steel lenses. Mugs, maps and inside of hatch covers are Ivory. Weapon barrels are dry brushed basalt grey. Everything is washed with diluted Army Painter strong tone ink. Final coat is matt varnish.
Nice little models. Not too many air bubbles, although the track edges were quite irregular. These will hopefully make it on to the table for some Force on Force games in the not too distant future.
Thanks for looking.
