As part of the Armor/Armored Build over at The Guild, I've recently painted a Trumpeter StuG III Ausf. E to test out some early war panzer grey paint techniques (in preparation for the upcoming Battlegroup: Barbarossa book).
Basecoat black, followed by a coat of Tamiya XF63 German Grey, then panelling in Tamiya XF66 Light Grey. Applied a wash of thinned Burnt Umber and a pin wash of Lamp Black oil paints. Pigments are Secret Weapon Miniatures Yellow Earth and Burning Sands. Stowage is by ValueGear and Plastic Soldier Company.
