This is a Blockade Runners badge or Abzeichen fur Blockadebrecher. The award was instituted on April 1, 1941. It was awarded to members of a ship that ran an enemy blockade and reached a German held port safely. It could also be awarded for scuttling the ship to avoid capture or serving aboard a ship lost through enemy action or being wounded during such an action while at sea. This is a nice unmarked badge. It retains most of its matte black finish and the silver on the anchor and eagle. Most of the silver from the chain border has worn away. The one problem with this badge is that the bottom catch has broken off. Other than that, it is a really nice badge. And yes, the third row does have the seven port holes. Due to the broken catch, the badge has been marked below normal market price. A nice filler piece if you do not want to pay $500+ for one that has no damage.
