German Flyer’s Commemorative Badge

The Flyer’s Commemorative Badge (German: Flieger-Erinnerungsabzeichen) was a German military decoration awarded to active and reserve personnel who had been honorably discharged from flying duties. Luftwaffe (air force) personnel qualified for the badge after having served as flyers for four years during World War I or had been honorably discharged after 15 years of flight duty service. However, one could also qualify for the badge if they became disabled due to a flying accident. If one was killed during the course of his flying duties, the badge was given to their next of kin.
No maker’s mark on the back, but a name (something with J. B…..) and a number (2644). With copy certificate of authenticity from 1998 stating that this badge is original and from that time.
