This is a single Leutnant zur See’s shoulder board. The rank was equal to a German Army Leutnant (2nd Lieutenant in the U.S. Army or Air Force, and Lieutenant JG [Junior Grade] in the U.S. Navy). The shoulder board has been removed from a tunic, and is of the sewn-in variety. Its backing is purple velvet. It measures 4 1/2″ X 1 1/4″. Overall, it is in very good condition.
