These original WWII 506th PIR ovals and jump wings are on uniforms that belonged to two different 506th PIR paratroopers. This style of 506th PIR oval is the type most commonly found on WWII 506th uniforms and in groupings.
The first oval and jump wings are on a uniform that belonged to a member of Company G, 506th PIR. The jump wings are sterling pin back wings.
The second oval and jump wings are on a uniform that belonged to a member of Company C, 506th PIR. The jump wings are also sterling pin back wings.
The final two photos show another original WW2 506th PIR oval that is not on a uniform. The photo of the back of the oval, shows what you want to look for on the back of these original World War Two 506 ovals.
