My father has a copy of a Colt 1911 a1 that was made in Argentina. It is a 1927 Argentine Sistema. It is well made and AFAIK, all the parts interchange with a GI 1911. He has always told me that it was made from the steel of a sunken German ship. I just read an article in The American Rifleman about the story. In reality, the story of where the steel came from concerns the Ballester Molina pistol. It is a .45 ACP pistol which at first glance looks similar to the 1911. The ship that was sunk off the coast of Argentina was the infamous Nazi ship, the Graf Spee. Although I've seen the movie "The Pursuit of the Graf Spee" and handled the Ballester Molina pistols over the years, the story of the connection of the ship and the pistols is fascinating to me.
