I have a handmade tool box made from Copper Sheet. The gentleman I bought it from said it was his dads. He was 63 years old and his dad had made it before he was born. It's copper sheet soldered on the edges with a handmade wooden tool tray and a galvanized metal lid. It also has heavy duty hinges made of brass as best I can tell. He believed the box to be 80-100 years old. It measures 16"x8 1/2" and 7 1/2" deep. Call me if you have more questions.
