Took a cruise through the BluRay to pull a bunch of screen shots to see what we could see.
This is just my speculation, so if I got something wrong or you have a different interpretation, comment away!
Part 1. Binoculars and tripod
We will start with the binoculars and tripod that Max uses overlooking the oil compound. The binoculars are probably 10x binocs with short leather strip sling/handle
These are fairly large binoculars, too big to be 6x or 8x nocs. Right eye piece and right front lens frame are missing. Brass center rod. They have a leather sling/handle with a single knot on the right side. He carries them on his belt until the camp overlooking the oil compound. Mounted on the belt by taking the sling over and behind the belt and then coming up on the front of the belt and hooking it over the brass hook (?).



Green tripod
It seems to be a British tripod for a heliograph. The arm holds a secondary mirror. Chain is supposed to have a thread protector cap on the end.
Note the bracket that limits the sling travel about 2/3 of the way down the leg. Max’s tripod also has this feature just to the right of the bottom of the hatchet handle.



Sling seen crossing his left boot ankle, then coming up to the sling bracket and looking over the left keg towards the axe.
