Well Mycroft, it was our very own Paddy who instigated the plan to get some bomb tags re-made as an A-2 accessory/zip pull. I guess you've seen reference to them on one of the Yahoo flight jacket forums... or Paddy's photos?
Aero Leather Clothing were selling these very same ones.....ummm....
..can't really use their site right now but try searching on the site under "bomb tag". Theyy may still have some left. Otherwise, you'll have to watch out for a real, vintage one. Good luck
