Here is a pic of my Burnt orange (paint code Z) 1980 Mk2 (hmmm that link says its an rs2000 colour) Anyways...
Just after being washed and the sun is out

Hasnt been washed in awhile and its pretty overcast.

Dunno how the pics represent the true Burnt Orange colour off the gun. But thats what it would look like after it fades abit =P
