I am trying to put together a shadow box for my of her father's military history. I want to place close to original insignia and medals along with badges and unit if possible. He was in USAAC until war ended. He was a Master Sgt, he was with 9th AF in England. with supply and maintenance unit. We think 1771st. what insignia did they wear in uniforms during that era? He went Tennessee Air National Guard and retired from there as CMSgt. I also need to know what was worn from 1946-1980 in USAF. He was deployed during Korea for a period of time. We know what medals he has, but don't know insignia or badges to try and locate.
