One of the most typical zipper pull tag fitted to a USAAF Flight Jacket during WW2 was the "Bomb Tag" safety pin tag.
These can be seen in various publications; Maguire's "American Flight Jackets & Airmen" Page 28 being a good example.
These Safety Tags have been specially made to give a true WW2 appearance. These are very limited in number and we are told cannot be repeated.
Anyone who has hankered after one of these should grab one while they can.
