An Apollo Command Module rotation hand controller with outer covering removed, presumed unflown, measuring approximately 6.75 x 9 x 2.75, with several etched and stenciled part numbers, including: "D1986400-1," "D2000770-1, 94580," "989552-1," and "SN1018, D989580." In fine condition. This piece would be used for controlling spacecraft attitude, and the 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. Lever switches at the front lock and unlock the joystick for operation, and there is a spring-loaded button at the top of the handle. In fine condition, with the top button slightly sticky. An amazing example combining both mechanical and electrical components, demonstrative of the craftsmanship and precision used in the manufacture of Apollo spacecraft parts.
