Apollo Block I Oxygen Control Panel by AiResearch Manufacturing Corp., measuring approximately 8.5 x 17.75 x 6.5. Designed to control oxygen supply in the Command Module, the panel features several buttons and inlets related to oxygen regulation, including: "S/M Supply," "Tank Pressure, "Emergency Inflow," and "Cabin Pressure." Also features a space for "Tool Storage," and options related to the PLSS (Primary Life Support System) and supply valve. Mechanical parts to reverse bear inspection stamps and several affixed green metal AiResearch labels. In fine condition. Panel includes a pressure transducer, a decidedly expensive component that was used in non-spaceflight systems and is often removed for separate sale. Deriving from the early pre-lunar Apollo mission, this Block 1 control panel was a vital instrument related to flight systems development and qualification of all unmanned missions.
