A huge bust of Kong's head, neck, and upper chest was made of wood, cloth, rubber, and bearskin by Delgado, E. B. Gibson, and Fred Reese. Inside the structure, metal levers, hinges, and an air compressor were operated by three men to control the mouth and facial expressions. Its fangs were 10 inches in length and its eyeballs 12 inches in diameter. The bust was moved from set to set on a flatcar. Its scale matched none of the models and, if fully realized, Kong would have stood thirty to forty feet tall.
