This is a lamp from the German first world war wreck called the Karlsruhe sunken in Scapa flow. I gave this lamp back to the Captain of the new ship Karlsruhe .He invited me to a party to celebrate the 20th birthday of the new Karlsruhe in Wilhelmshaven 1n 2004. The really strange thing is that the city of Karlsruhe in Germany is twinned with Nottingham ( My home city ).
