The Zambians painted their vehicles in the old British Army matt camouflage green, with blotches of cream and chocolate brown blotched camouflage using short strokes of a wide brush to create the disruptive pattern.
You can see a Bedford RL (by 3D FV models) and a Land Rover (by Airfix) in Zambian disruptive pattern camouflage.
The Crocodile towing a stores trailer is by S&S Models and in Rhodesian disruptive camouflage pattern. The Bedford RL open cargo area is by 3D FV Models but I am not sure if these still exist. Skytrex also did a reasonable Bedford RL which may now be re-released by 20mmZone Models.
