Dr Who reveals new weapon in his fight against the Daleks (short story)

Dr Who reveals new weapon in his fight against the Daleks was an in-universe advertisement featuring the Daleks which was printed in the pages of TV Century 21 in 1965.

It was set in-universe and had a narrative, with Lincoln International's new product the Neutron Exterminator being presented as a "triumph for British scientists". It continued the story arc of the Daleks' premature presence on Earth (in comparison to the main The Daleks strip) but notably indicated for the first time that the First Doctor was involved in the 2060s Dalek invasion of Earth. Uncharacteristically, he is described here and in later advertisements as developing weapons for the war effort. The only mention of the Doctor in any story covering the invasion which is considered valid by this Wiki was in Return of the Elders, during which Kaslan acknowledged that "another" would fight the Daleks sometime in the future once they returned for another invasion.

Summary
To aid in the never-ending fight against the Daleks, the London section of Lincoln International Ltd develops the Neutron Exterminator with some undisclosed assistance from Dr Who. A boy demonstrates the weapon on a small group of invaders, dealing complete destruction to them. Lincoln urges the public to not be caught defenceless and announces that the Neutron Exterminator is available from all good toy shops for the small price of 24/11.
