Cast Iron Roof Finial Base

The item appears to be an antique or vintage cast iron roof finial, specifically the base or a decorative element meant to be mounted vertically. It is constructed from heavy cast iron, evident from its rough, textured black surface and substantial appearance. The finial is shaped somewhat like a shield or an elongated spade, with a rounded top and tapering sides that flare slightly towards a broader, flatter base. Its overall color is a dark, matte black, likely from either original paint or a long-developed patina of rust and dirt. There are visible signs of aging and wear, including surface pitting and irregularities characteristic of cast iron that has been exposed to the elements. Three prominent brass-colored Phillips head screws are visible, indicating it has been mounted on the wooden substrate, which appears to be OSB (Oriented Strand Board). These screws are clearly modern and not original to the piece, suggesting it has been repurposed or reinstalled. A notable feature is a circular indentation or raised boss near the bottom center of the item, which appears to contain a faint, possibly embossed or incised, mark that resembles the number “G.” or perhaps a stylized symbol. This mark could be a manufacturer's identification or a pattern number. The edges of the finial are thick and somewhat uneven, which is typical of cast iron manufacturing of earlier periods. There are no obvious signs of recent damage or repairs beyond the natural wear and tear. The craftsmanship suggests industrial-era production, likely late 19th to early 20th century, given the material and casting technique. Its quality is robust and functional, designed for durability outdoors, and the rustic patina adds to its antique appeal.
