After years of tracking down another Lewis, with known interesting history, I finally found and bought it. This one is in a sad state with missing parts, as seen here: This gun came out of the fishing boat: Skaftfellingur. On 20 August, 1942 this boat was sailing to England when it spotted a sinking U-boat, the U-464 which was a "Milk cow" a special U-boat supply boat. The U-boat crew were rescued by the Icelandic fishermen, with only 2 cassualties. Captain Páll Þorbjörnsson was worried having all these Germans onboard, as he was only armed with a 5 shot rifle and a "90" round machine gun. This Lewis, is that gun. It came from the family of Capt Páll (Paul) So this Lewis was likely pointed at a U-boat during the war. For detailed info in this incident, see: http://dubm.de/en/the-skaftfellingur-and-u-464/
