Was any part of the tunneling machine saved for posterity or public viewing?

The tunneling machine was owned by the original manufacturer, Hitachi Zosen, and the decision on what to do with the machine was theirs to make. Hitachi Zosen worked with The Port of Seattle and the Museum of History and Industry to preserve several pieces of the machine. The Port of Seattle received pieces of the cutterhead, and MOHAI received cutting tools and the machine's control panel. Most of the machine was recycled or preserved for use in other machines.
