Paris Gun
Two 42 cm M-Gerät guns were surrendered to the US Army at Spincourt in November 1918. One was taken to the United States and evaluated and then put on display at the Aberdeen Proving Ground, while the other was left unassembled in its transport configuration. Both were scrapped in 1943 and the early 1950s. World War I veteran Emil Cherubin built a replica of an M-Gerät, which toured Germany and appeared on a few postage stamps. The Paris Gun has historically been confused with the M-Gerät since World War I.
