My father bought the back of a German torpedo at a scrap yard 14 years ago. It came entangled in a fishing net when fishermen took the net up on the North Sea. My father began to disassemble the back to recover the engine and gyroscope. Is it possible to find out the name of the U-boat, through the markings on the gyroscope? Could I have some more information? If you have pieces of a torpedo, please place pictures here.
