Image of 2015.029.006 - Zap Gun Award Presented to Paul M. Cook, 1968. Zap Gun (A) and mount (B) are two pieces which can be separated. The gun (A) is the original, first zap gun ever made. The barrel of the gun is  brass shaped like an oblong sphere that is tapered at the ends. When trigger is pulled, nose of the barrel opens up to release heat. In the middle of the barrel is a embossed ring around the widest part. The back end has a small circular cutout which exposes a transparent glass piece (light?). Glass piece has cylinder base with a protrusion out the top. The black, plastic handle conforms to the bottom of the barrel from end to end. The end of the barrel that opens attaches to handle with a J-shaped metal piece. Handle has hash marks pressed into plastic. Very base of the handle has a black rubber tube attached. The bottom of the tube has a gray, four-pronged outlet for connecting a power source. The gun attaches to the award base (B) by sliding into a black, metal plate. The plate is attached diagonally to a black, metal mount which is screwed into the base. The base is a transparent, acrylic square. Glued to the front, center of the base is a square, brass metal plate. Inscribed on the plate "TO  /  PAUL M. COOK  /  for sticking to his guns  /  THE FIRST ZAP GUN  /  produced in summer, 1965 and presented by  /  Heating and Devices Department  /  June 1968".

Image of 2015.030.001 - Raychem 9kv Surge Arrester, c. 1996. Third generation surge arrester designed by the Raychem Corporation for the European market to provide lightening protection for electrical utility grids. The surge arrester is produced with novel ceramic and metal chemistry that is covered in a housing of weather and voltage protective polymer.  A circular metal shaft with an octagonal shape embossed at each end runs vertically through the center of the surge arrester. "SHN 206" is inscribed inside the octagon on both ends. The polymeric outer coating is colored red and covers the majority of the object except for a small portion at top and bottom. The shape of the surge arrester is symmetrical with various disks staked along the central shaft. Two sets of one large and one small disk appear at center with a wide flat cylinder appearing at top and bottom. The metal bolt at the top is not part of the artifact, but is used for mounting purposes only.
