    The 2 outer pins are stationary & the center pin operates the dial(probably .001's of an inch) to measure flatness of a surface or similar applications.

    Good call B'buss, it is a dial indicator but unlike any that I have used!
    Turns out it is a lens clock.
    A lens clock measures the curvature of a surface, but gives the result as an optical power in diopters.
    Measures the concave & convex (+ -)
