Bidspirit auction | A Trio of Heavy Cast

A Trio of Heavy Cast Iron Spherical Projectiles - A trio of heavy cast iron spherical projectiles, likely historic smoothbore ordnance or industrial crushing balls. The set consists of three solid cast iron spheres of graduated sizes, each exhibiting a characteristic cast finish with evidence of heavy surface oxidation and pitting consistent with long-term burial or environmental exposure. The mid-sized sphere shows significant delamination and scaling to the outer surface, revealing a dense, dark iron core beneath. These items are typical of historic military shot, such as cannonballs or grapeshot, though they also bear a strong resemblance to industrial ore crushing media. No maker's marks, stamps, or military broad arrows are legible on any of the specimens due to the extensive surface corrosion. Smallest sphere diameter: 1.5 inches Mid-sized sphere diameter: 4.75 inches Largest sphere diameter: 7.75 inches.
