3/30/20 - This is an original WW2 wartime production T14 Nambu magazine. The magazine has a blued tube and aluminum base. The spine is 3 digit serial numbered 688. There is some rust and patina speckled throughout the left side of the tube, and some wraps around on to the spine of the magazine. See photos. Spring is strong and fully functional. Bluing is otherwise excellent - priced based on condition.
