    Civil War Parallel Ruler - Inventory Number: MIS 107

    Made of ebony and brass.  Navigators use these parallel rulers for laying off a specific course on a chart. They were first invented in 1584 by a Frenchman named Mordente, but only became common in navigation in the 18th century. Very nice original example.
