    Description

    Gerber GraphAnalogue.
    A Graphical-Numerical Computing Device.
    Performs computations directly on graphs, curves, and recordings.
    Is also used on graphical work where reading, plotting, and interpolating
    are of the essence.
    Operates smoothly.
    Fine condition.
    Is missing one small indicator disc (no. 6 of 0, 2, 4, 6, 8, 10) on short round spring
    that is only an aid for reading the long triangular spring that is the heart of the
    instrument. No. 8 is in a small plastic bag and can be reattached.
    The long triangular spring has 100 calibrated coils, of which every fifth is colored
    blue-green, every tenth red, and the others white.
