(Wikipedia) The Krupp 28-cm-Kanone 5 (E), in short K5, was a heavy railway gun used by Germany throughout World War II. ... A K5(E) is preserved at the United States Army Ordnance Museum in Maryland [recently moved to Fort Lee, Virginia]. It is composed of parts from two guns that shelled Anzio beachhead during World War II. They were named Robert and Leopold by the Germans, but are better known by their Allied nicknames - Anzio Annie and Anzio Express.
