Camfield's Fairy Milk Chocolate

Camfield's Fairy Milk Chocolate was a brand of chocolate bar on Earth in the 20th century.

History
Having escaped the Robot Yeti's deadly web at Monument tube station, Jamie McCrimmon and Driver Evans stumbled across St. Paul's where there was a platform vending machine selling bars of Camfield's Fairy Milk Chocolate.

Fancying some chocolate, Evans tried the machine without inserting any money and discovered, to his surprise, there was a chocolate bar in the machine's open compartment. (TV: The Web of Fear)

Behind the scenes

 * The name Camfield's Fairy Milk Chocolate was obviously inspired by the real-life . It was an in-joke reference to director Douglas Camfield, and complied with the BBC's policy of not displaying brand named products on-screen.
 * This reference originates from the reconstruction of the currently still missing episode three, using John Cura's telesnaps linked up to the original soundtrack, as featured on the 2013 DVD release of the story. It does not appear in the original episode, nor is it represented in any of the existing telesnaps. The animated colour version of episode three depicts the chocolate bar wrapper as being purple with white lettering, the uniform colours of Cadbury Dairy Milk.
 * As episode three has yet to be recovered, it remains unknown as to whether the chocolate bar wrapper was shown in detail on-screen and what name it bore. Bearing in mind the vending machine shown in episode three was unbranded, it is likely the wrapper may have been likewise.
