A friend of mine brought this over - he bought it at a garage sale for $5.
It is some kind of a measuring instrument. Has 3 legs that it stands on and a center point that screws up and down. I'd say it's at least as precision as a micrometer.
Maybe a device for checking lenses or somesuch?
I told him someone on tractor talk would probably know.
Any guesses?
