Dalek (The Space Museum)

An empty Dalek casing was among the exhibits in the Morok Empire's Space Museum on Xeros.

History
The empty Dalek casing was present in the Space Museum on Zeros when it was visited by the First Doctor and his companions. It was the first time Vicki had seen a Dalek, having learned about their invasion of 22nd century Earth. Whilst briefly captured by the Xerons, the Doctor hid inside the shell before being discovered and captured by the Moroks. (TV: The Space Museum)

Several theories were proposed as to how the Moroks had acquired a Skaro City Dalek casing for their museum. Historians who studied the Dalek race theorised that the casing might have been a discarded piece of Dalek refuse that the Moroks had claimed or had once belonged to a Scout Dalek that had been overpowered. (PROSE: The Whoniverse) The Time Lords believed that the Dalek had been one of the combatants of the Thal-Dalek battle, its inert shell claimed by Morok scouts who visited Skaro. Their record of Dalek activity indicated that the casing was exhibited in the museum in the 22nd century, prior to the 2150s Dalek invasion of Earth. (PROSE: Dalek Combat Training Manual)

According to another account in the Dalek Survival Guide, this Dalek was one of a group who left their fake Time-Space Visualiser on Xeros for the Doctor to acquire, but was killed and displayed by the museum's curator for not paying admission. (PROSE: Dalek Survival Guide) The remaining Pursuer-Daleks were slatted silver Daleks supported by dark-domed War Machines. (TV: The Chase)

Behind the scenes

 * The Dalek Handbook suggested that the Moroks visited the Dalek City on Skaro some time after the events of The Daleks and acquired this casing, restoring power to the city in the process. However, this is only framed as a suggestion.
