This is a set of two cast iron fence toppers with a Fleur De Lis style design on the finials, these each measure 39" long and about 5" tall.  I am not sure the history of these, they were and estate sale purchase.  They are not completely straight, if the bottom flat part was a horizon line, it would not be a straight line. Otherwise these are very solid and each have nine finials with some natural age, wear and patina.  These could be used for any number of projects, please see the pictures closely and if you have any questions please ask.
