Planet of the Daleks featured a previously unseen Dalek, Dalek Supreme, with a distinctive black and gold casing. That Dalek came from Terry Nations private collection of Dalek casings. By carefully looking at physical characteristics one can trace the history of these casings through pictures appearing in magazines and elsewhere. Many think Terry Nation's personal Daleks are movie props from "Daleks Invasion of Earth 2150 A.D." A careful study of the Daleks in that movie identifies specific characteristics corresponding to the Daleks in Terry Nations collection. Even more careful study says that some of the Daleks in the movie were built for a stage play, Curse of the Daleks.
