Estate found!

This product is an original khaki US Marine Corps Corporal Chevron from WWII/Korea era. The chevrons are militaria items and are related to the US Marine Corps. The product is a patch and is from the United States.

Previously never sewn on, it appears.

I am not an expert in insignia. If I have mislabeled or misinterpreted anything I apologize in advance. These came from an estate sale, so I have no personal historical information.
