One of Hitler's biggest long-range guns will be scrapped in the near future after rusting since V-E Day at Railway siding near Grafenwoehr, Germany. This Mammoth piece, boasting two 100-foot barrels of 820mm. Each, had been held in readiness for a planned attack on Gibraltar. A similar gun was used during the siege of Sevastopol, Crimea, in the summer of 1943. Here a U.S. Army officer inspects the blown-up recoil mechanism. July 22, 1949. (Photo by Acme Photo).
