On the left is the 'Dark Coyote Brown' 1000D material that I use on my Delta Force Strike Vest repros as a surrogate for 'Nutria Brown'.
Comparing it to the fabric on a legit SADF Pattern 83 Rucksack, the colors are almost identical. Main difference is that the legit SADF Nutria material is a little lower saturation and less 'shiny' overall, but this might just be from everyday use and UV fading more than anything.
Just pleasant little surprises.
