Vickers gun
From Tardis Wiki, the free Doctor Who reference
A Vickers gun required water to function. On 11 November 1914, headmaster Rocastle ordered Ashington to get water for the Vickers gun as they prepared to defend Farringham School for Boys against the Family of Blood. It was later handled by the students, and fired at the animated scarecrow the Family brought to fight. (TV: Human Nature)
