Pretty rare 30s 17 inch long Talon zipper. Very cool feature of a locking pin on body of zipper that does not allow to fall down when pull is laid flat. This would be used for a jacket or something that unzips all the way. Teeth work great. Negatives are: upper right stopper missing, as well as bottom left rivet. See photos for a better look. Please send any questions. ALL SALES ARE FINAL, NO RETURNS
