This is a pair of Lt. Col. Rank in the current issue full size in sterling silver. How come current issue full size statement? It appears from WWI to WWII the size grew by a 1/16 of an inch and in the early 1950’s they grew by another 1/16 of an inch. So these are the current size. This is sold in a set of three , two for Class A uniform and one for the overseas hat. We believe we are the only current manufacturer of this rank in sterling silver and they are hallmark W32USA, STERLING.
