Antique Weather Vane Arrow with Old Blue Glass Lightning Rod Ball

Here's a weathervane arrow and glass lightning rod ball we salvaged from an old Western New York farmhouse! The arrow is made of cast iron and shows lots of age and wear with plenty of pitting and patina! It measures 16 1/2 inches long and 4 inches high. The lightning rod ball is blue with swirling in the glass. One opening has some chipping but overall, this piece is in very good condition. It is around 5 inches from top to bottom. These items were together for more than a Century on top of the old house so we are offering them as one lot for a reasonable price. $100 both!
