Create a high-resolution 3D model of the Ottoman-era ‘Great Turkish Bombard’ (Şahi Topu), cast in aged bronze or iron with realistic surface textures. The cannon should appear massive and heavy, with slight patina, rust, and wear. Avoid modern or polished surfaces. The barrel must be segmented and slightly tapered, supported on robust stone blocks. Include detailed floral engravings and ornamental patterns typical of 15th-century Ottoman craftsmanship, but exclude any calligraphy or tughra. Render from a left profile angle, with a white or neutral background and realistic lighting that accentuates the metallic texture and aged surface
