Dalek metalworker
From Tardis Wiki, the free Doctor Who reference
Alongside Dalek transport officials and Dalek miners, Dalek metalworkers were one of the castes of Daleks represented in significant numbers at one Brindigulum held on Valkenine at some point during the reign of the Golden Emperor. The Brindigulum had been formed so that the various Daleks could discuss ways to raise the efficiency of the mining operation on the planet. (PROSE: Hostage!)
