Extremely Rare Piece of History. During WWII Submarine U-68 sank many Allied Cargo and Supply Ships until US Aircraft Carrier USS Guardalcanal sank it in 1944. While sinking to the bottom off the Portuguese Coast the ballasts floated and were picked up and made into souvenirs. This bar shows signs of scaring, age and has blemishes but remains intact. Most definitely a show stopper in your WWII display. Please view pictures for quality and condition.
