Seldom-offered Block II Apollo Command Module Rotation Control. Controller housing measures 7.25 x 5.5 x 3, with its attached umbilical measuring 104″ long. Honeywell identification plates to one side identify part as “Control Rotation; Mfr Part No. DCG166D2; Contract No. NAS9-5269; Mfr. Serial No.10028DAK1016; manufactured 26 SEPT 1966.” Spring-loaded hand controller remains quite tight and returns to neutral, and the locking mechanism is a bit loose, but still works when slight pressure is applied to the controller. Handle retains the trigger switch which would activate the astronaut’s headset. In fine condition, with several labels and stamps to housing, as well as scattered surface marks.
Also referred to as an attitude controller or rotation hand control, this was used for controlling the spacecraft attitude. Handle pivots at the palm for pitch up/down, through the center of the handle for yaw left/right, and inside the housing for roll left/right. Levers in front of the handle lock or unlock the handle for operation. Controllers of this type are considered quite uncommon and are highly prized by space collectors. RR Auction COA.
