12/4/18 - This is an earlier / pre WW2 style T14 Nambu magazine. The magazine has a nickled tube that's in excellent condition. There's only a few small areas of discoloration - as shown in photos. The spring is strong and fully functional. The spine of the magazine has serial number "700". There's light discoloration on the base, but again this magazine is in excellent overall condition. Guaranteed original and authentic.
