In 1921 the Airship Pilot Badge (while it looks like a wing it was never officially called that) was introduced by the US Army. This is a very well made sterling silver museum quality reproduction of that badge 2 inch with pinback. The 2 inch wing was never official. Not many of these badges were ever made and are missing from many collections after all how many Airship Captains were there. Actually there were about 150. Also it is interesting to note that 6 know designs existed of this badge. The badge was abolished on Feb. 20, 1940.
