Working on my own, though locally sourced work and supplies scrounged thanks to Ye Olde Internet. I'm doing essentially the Supertrooper version. I've got 1-7/8" nylon SCUBA strapping that's close to the original, even if the weave doesn't have the correct diagonal grain to it. I found a place in the UK that has perfect 40mm white cotton strapping, with the correct weave, even. I'll post up a picture tomorrow. It fits the pack-hook rings perfectly. Those and the rest of the buckles and rings so far I got from FullMetalFett, and they're bloody brilliant.
So here's my question. Those upper pack straps... I know they look through the ring and are riveted. I know the other end is rigorously sewn to the main straps. But there's a gray area there. Is that strap completely doubled -- one length folded in half and ends lined up, with that stitched down, and then riveted closer to the ring? Or does the bit fed through the ring end short of the upper portion, closer to where it's riveted? I'm hoping another set of eyes or three squinting at the few images we have of visible pack straps will turn up a semi-clear answer.
