Miniature Badge For Naval Pilots On Seaplanes (Abzeichen für Marine Flugzeugführer auf Seeflugzeugen). The Badge For Naval Pilots On Seaplanes was originally introduced on 31 May 1913 by 'Kaiser Wilhelm'. All soldiers, regardless of rank, were eligible once they successfully completed the training at a naval aircraft station and thus received a certificate of proficiency as a naval pilot. This is a 21mm sized cut-out variant miniature on stick-pin. The gilded gold miniature is showing stunning details and polished highlights. Rare original miniature in very good condition!
