WWI 2nd Air Park Artillery Uniform with Aviationand U.S. collar disks, Aviation SSG patch, overseas stripe, discharge stripe,and excellent 2nd Air Park Artillery patch. The patch is very nice and has a bullion wingwith the number two on top of two circles and crossed cannons. This is a rare patch and I have never seenanother one like it. This was WWI’sversion of Air Defense Artillery. The uniform itself has some visible repairsthat are of the period. The uniform wasfound in a rag factory in Toledo Ohio in 1976 and has been in a privatecollection since that time.
