Here are some views of the Africa Korps Panzer III.
The model was undercoated black, followed by PSC German Tank Yellow.
The track links were undercoated black and dry brushed a mixture of black and hull red. The final dry brush was Citadel Ryza Rust. A shade wash of Earthshade finished the track.
The edges of the armour were dry brushed with Army Painter Skeleton Bone, as was the stowage.
This is my attempt at the view on page 5 of the Osprey book on the Panzer III.
