Does anyone have an idea of what this is?
Sorry for the poor photos.
It is about 4 1/2 to 5 foot tall. It is fairly heavy, my guess is over 20 lbs.
There are 2 vertical metal columns. Near the top are two red painted metal rectangular blocks, that can slide up/down the columns with locking bolts. At the center of each red block is a vertical hole with a cylindrical bushing holding a thin cable running vertically through and down to the tri-legged base. The cable is the same as what you’d find on bicycle caliper brakes. There is another rectangular red block just above the 3 legged base. Each of the 3 legs at the base has a threaded adjustable spike for leveling.
The second photo shows a closer view of the red blocks. One has a metal platform which holds a bubble level and a round dial marked 0, 10, 20, 30, etc to 90 with 10 divisions between each.
I will try to post the second photo in the following post. The site won’t let me imbed more than one photo.
