I'm pretty confident that the actual harness was a found item, most likely used to carry some sort of oxygen tank. Myself and others have searched forever for one like it but never came very close.
These were created in the UK and then shipped to the US.
As for trying to track down the harness strap materials, I would not look specific to country. I would just look everywhere. Wherever it is found, is the place we would be willing to buy it from.
