Impossible Restoration! Rusty Antique Mystery Tool Restoration

This mystery tool was locked in rust for nearly 150 years. It looked like a metal puzzle—heavy, jammed, and covered in thick layers of rust. No labels, no clues—just mystery. As I started restoring it, each part began to reveal a story. Slowly, the rust came off, the gears moved again, and the secret finally appeared—it was an antique key cutting machine. Once used by locksmiths over 150 years ago, this forgotten relic is now working again after decades of silence. Watching it come back to life was pure satisfaction.
