Collection of thirteen Apollo Command Module Block 1 and Block 2 mock-up control panel components, primarily consisting of electroluminescent overlays. The Apollo spacecraft saw the first application of electroluminescent lighting, which generated a blue glow that allowed astronauts to sleep or run exercises that required low light within the module. This grouping includes a mock-up audio control panel marked "6" on the face, featuring four knobs (attached with metal axles on wooden blocks, no electronics); a mock-up audio control panel featuring text related to volume controls and five knobs mounted in a similar manner, with some text plates missing; a telecommunications panel marked as "225" on the face, with part number "V36-762165-41" and several wooden blocks on the reverse; two different communications panels with markings related to volume and radio controls (one marked on the reverse with a manufacture date of "2-71"); a panel marked "16" with a long slot on the front and text associated with the docking target and COAS power, marked on the reverse with a manufacture date of "3-69"; a panel marked "VHF Antenna," with manufacture date of "12-68" on the reverse; a panel marked "229" on the face with circular holes for EPS groups, marked with a manufacture date of "12-67" on the reverse; a long rectangular panel for power systems, marked with a manufacture date of "12-67" on the reverse; three large trapezoid-shaped panels with text for environmental, propulsion, and stabilization control systems, one with a manufacture date of "12-67" and another with a date of "2-69," the third undated; and a panel with sections for "SPS Gauging," "Suit Compressor," and "Glycol Pumps." In overall very good to fine condition.
