Narishige MO-155 Joystick Micromanipulator.  Single-axis oil hydraulic.  From the 2003 Narishige Catalog:  Oil hydraulic single-axis fine movement and three-dimensional operation with single lever.  This model adds oil hydraulic Z-axis movement capability via the manual joystick, which is equivalent to having an oil hydraulic joystick and enables three-dimensional fine movement operation.  The MO-155 keeps the point of the needle steady for smooth, accurate operation.  Free adjustment of the movement ratio and tightness of the lever make this model very easy to use.  It is in nice operating condition and still in the original box.  This box does NOT include the pipet attachment bar.  The 2003 list price was 3,250.00.
