1919 Observer Wings. These wings were authorized on Jan 25, 1919 as the new Pilot wing designed by Mr. Herbert Adams of the Commission of Fine Arts. This wings was hated and lasted only until 14 Oct 1921. The reason it was hated most people believed the government took left over buttons for the wing center. It does look like a button. This is a museum quality reproduction made in Sterling Silver of the very rare Blackinton version. Most reproductions are of the Meyer version, you almost never see the Blackinton version.You almost never see a real wing or even a restrike of the Blackinton. This has a center clasp pin back. A must for any collector to fill that hole in your collection.
