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 and lightly aged to give a true WW2 Vintage 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.
