That makes me wonder if those are Canadianicon made. There is a site called Trigger Time by Mark Bando about the 101st ABN. He did a study on the grid sizes on the Helmet Nets (not color though) on some of his Photo's he has . As a kid we would look for old fishing nets for our Surplus Store Helmets. Most of the Netting had nylon in them and never looked right. I was even discerning back then, scary !
