A detailed 3D model of an old-fashioned cannon with a short, thick iron barrel mounted on a wooden carriage. The barrel is decorated with ornate engravings and embossed patterns, giving it a regal or ceremonial look. The wooden carriage is weathered, reinforced with dark metal, and features large spoked wheels. Subtle gold or bronze accents highlight the decorations. Stylized but clean design, game-ready low-poly geometry, no background, neutral lighting. Realistic materials: aged wood, dark iron, slight rust, and polished ornamentation.
