This record contains one part from an electron beam gun. It is a cylindrical object composed of circular metal and plastic components attached together with four thin metal rods. In between these circular components are various other metal components. There are several thin metal wires encased in ceramic which are attached to several of the plastic and metal components. One end of the object ends in a large metal component which is circular in shape but has four protruding pieces. The other end of the object ends in a large circular metal component with metal tabs protruding downward, and the four thin metal rods protruding outward.
