Create a realistic game-ready 3D model of a soviet power transformer with early-1990s Eastern European industrial design. Materials: painted steel in worn and dusty grey colored, with scratches, chipped paint, slight rust at bends and around mounting holes, dust and grime in corners. No labels, no logos, no readable text. Clean topology, medium poly; separate parts for backplate, ring/cradle, strap/latch, fasteners.
