RARE PA NG 28th Div Aviation DUI Crest Pin 103rd Observ. Squadron
Outstanding ORIGINAL 1930’s example of this very difficult to find DUI. 28th Division Pennsylvania National Guard Aviation Section. This design was approved in 1931 and being hallmarked by noted Philadelphia jeweler, S. Eby, it dates from the 1930’s. Extremely high quality, as Eby was known for first rate insignia. Enamel is perfect (the photo picks up some strange glare). Has screw post and original nut. Also identified as the 103rd Observation Squadron during WW2.
