A two very hard to find collar size insignia rank for General of the Army, also same one used for Admiral of the Navies and General of the Air Forces. These are made in sterling silver. Silver ones are even harder to find than the regular collar ones. What is interesting this size rank was the only 5 star insignia that could be worn by all services. The full size was not used by the Navy and the Navy mid-size(raincoat) was not used by the Army. Sold in a set of two. Clutch Backs.
