Dalek War Machine

By one account, the Mark II Travel Machines were the initial Dalek designs by Davros following his life-support chair, the Mark I Travel Machine. (PROSE: The History of the Daleks) The design was ultimately finalised with the Mark III Travel Machines, (TV: Genesis of the Daleks) with the Time Lords understanding that Davros had abandoned his first two prototypes. (PROSE: Dalek Combat Training Manual)

In contrast to the earlier models, the Mark III worked with several different power sources, allowing them greater mobility and not restricting them to the static electrical power their prototypes used. A ring of solar cells was constructed about the midsection of the casing. In cases of need, there would be a battery pack inside the casing. An optional addition, useful for overcast areas, was a small dish that could be attached to the back of the Dalek to collect broadcast power. (PROSE: The History of the Daleks)
