Found this at a local estate sale for 5.00. It looked interesting. Has no makers name or any other info. Has calibration numbers in 2 places. Measures 12" tall X 16" long with adjustable arm. Base is 6" wide.

Maybe part of a large telescope (or other optics) mount?
I'm thinking the adjustable circular disk on the rod is intended to be used as a counter-balance weight. ?
