The strange tale of the elusive Buzz Saw Dalek

The Battles in Time trading card range has a very interesting Dalek variant included in its 'Daleks vs Cybermen' set, which depicts a Dalek armed with a buzz saw instead of the standard plunger-shaped manipulator arm attachment. Was this simply a Dalek variant created for the trading cards, or was there actually a buzz saw Dalek in Series 1 of Doctor Who? All footage and music is the property of the BBC
