Who made this tripod?

[Brit plumber]

I believe it's 2 standard Rifle slings, not the X Strap. The X strap is from a ammo box carrier I think or possibly a universal harness as I've seen some with short straps and some with long. If the short straps are fitted, you couldn't even get it over a shoulder never mind on your back. Let's say that an entrepreneur came up with a story to sell scrap webbing at a profit.
