I'm thinking some sort of balance or active counter weight for either a telescope, camera rig, or surveying equipment.

It's a topographic mirror/prism. Used for setting out points by surveyors.
 Those are actually pretty cool gadgets. If you look into it, it makes you look 90 degrees left and right by using prisms. (I'm a topographic surveyor by degree.)

been obsolete since GPS came into the survey realm. that one would have cost about $25 bucks and the other one in the pictures was about $35 when I bought it.
But of course they don't wear out. |

Get off my lawn!

Some things never change with technology, but some sure do. Today I received a new catalog in the mail with all sorts of very high end GPS surveying equipment but right up front was a machete. That part will never change. There will always be brush and weeds to hack through.

Used to carry one along with a hand level, plumb bob and the old tac ball, and a two pounder.
