Hi Daryl,

Series 3 - Final Camouflage Scheme
Series 3 units still in service in the late 1980's at this time also received the Auscam scheme, as did any series 2 or 2A specialist vehicles still in service (Such as workshop vehicles and ambulances). This camouflage scheme used olive drab, black and tan in a set pattern. The olive drab was the base colour of the vehicle and the other 2 colours were applied over the top.
Painting of vehicles started at front line units with some units like schools never repainting their vehicles. Not all series 3 land rovers received the camouflage paint schemes.
The actual pattern applied to vehicles appears to have been a slightly modified version of what was applied to the 110 Perenties, although a couple of variations appear to have been used.
The paint in those three satin colours are still available from Protec and even have their NSN's on the tin still. It is enamel and quite easy to paint with.
Camouflage green (342-1166)
Camouflage tan (342-5265)
Camouflage black (342-7165)
Cheers,
Pete
