I have no idea, but cant help but notice the tight basketweave at the knot ends just above the tassels. Is there any hint of crimson in the folds at the knots? Here's one I found on a google search with wider/looser basketweave at the knots. Like I said, I really dont know anything about uniforms so dont know if that is significant, but I'd venture its much harder to make the tight basketweave like yours than the looser version on this one.

Im leaning toward buff as the original color or yours, but I dont know enough to know why.
