Three-inch A.A. cartridge cases. Cartridge cases for three-inch antiaircraft shells are drawn from brass cups which are themselves formed from flat discs. After they come from the cupping press they are washed to provide clean surfaces for future operations and are conveyed in basket trucks to annealing furnaces. Annealing will remove any strains set up in the metal by the cupping press operations
