The Bendix Upper Deck Turret is an all electric turret used exclusively in the PBJ Mitchell bomber where it protects the upper area of the plane. There are two basic models: the Bendix 250CE-3 and the Bendix 250CE-4. The Bendix 250CE-3, used only on early models of the PBJ, is mounted just back of midship. When waist guns were introduced to the PBJ, the Bendix 250CE-4 was designed for mounting just aft of the pilot’s compartment. The two models are essentially alike. The description of the Bendix 250CE-4 in the following pages will also enable you to operate the Bendix 250CE-3.
