This exceptional American weathervane, crafted around 1885 by B. Harris & Co. of Boston, Massachusetts, depicts a dynamic horse-drawn fire pumper rendered in molded sheet copper and zinc with brilliant gilt surface. The piece captures the dramatic energy of nineteenth-century firefighting culture, showcasing the muscular horse in full stride as it pulls the ornate pumping apparatus, demonstrating the master craftsmen's remarkable attention to mechanical and anatomical detail. As both a functional weather instrument and a decorative art object, this rare weathervane stands as a testament to the golden age of American folk art and the artisanal trade of copper weathervane manufacturing.
