Hi Miloslav
The site posted by SnakeEye is a good one; also here are some additional photos:

What to do when your Chevy gets stuck: dig and roll out the sand channels and sand mats.
T (NZ) Patrol vehicles. 'Te Arawa II' (?) on right.
R (NZ) Patrol setting out from Jalo Oasis. Note Maori 'Tiki' in green on right clamshell bonnet.
R Patrol again.
This time vehicles of the Guards Patrol. Probably overall Canadian Sand with 'LOUISE' stenciled in black over desert pink (?)
Hope these help.
