Item description for Two NOS South African Defense Force Phalaborwa Commando Unit 13 Shoulder Boards

NOS South African Defense Force Phalaborwa Commando Unit 13 Shoulder Boards - They are NOS ("New, Old Stock") with a vintage price written on the back of one. The plastic things on the back are actually screw-down nuts, you apparently thread the epaulet through the tab then poke the threaded pin through the epaulet and screw the plastic piece on. Of some vintage and not easy to find.
