This is a museum quality reproduction of the WWI Pilot wing design by Shreve and Co. This wing is rather large measuring 3 1/4 inches. This wing is made in sterling silver and the US letters gold plated in 24karat gold. The silver wing is mounted on a brass plate and black wool is sewn between them in the WWI Style. The Shreve wing is an extremely rare wing and considered one of the best designs of the WWI era.
