Two versions of Kong's right hand and arm were constructed of steel, sponge rubber, rubber, and bearskin. The first hand was non articulated, mounted on a crane, and operated by grips for the scene in which Kong grabs at Driscoll in the cave. The other hand and arm had articulated fingers, was mounted on a lever to elevate it, and was used in the several scenes in which Kong grasps Ann. A non articulated leg was created of materials similar to the hands, mounted on a crane, and used to stomp on Kong's victims.
