WWII US Service Shirt for 13th Armored Division-This shirt is produced in an olive drab elastique wool that is in very good condition. There are breast pockets with scalloped flaps. There is a seven. button closure. The left sleeve has a 13th armored patch plus a rank patch for a staff sergeant. The right sleeve has the same rank patch. The right side, above the breast pocket, has an Honorably Discharged Veterans Insignia, aka “The Ruptured Duck” 😊. It is a size medium but there is no size tag. There is a small tag inside with the number 41. Very good overall!
