Made from the copper from the electric motors from WW1 Imperial Navy German Uboat U-155. Detail is still fine unlike many that are dented, bent and polished out -particularly the mast lines! 18x13x1.5cm approx Very interesting item made from scrap of German Submarine after the war.
Please see pictures for condition I've gently rubbed a bit of Brasso on the front side to see the condition better.
