Lot 524: An engineering mock-up of Skylab control panel #16, nearly identical to the flight version launched in the Skylab Workshop during May 1973. The panel was located in the central area of the Workshop near the crew quarters section. Panel measures 35 x 15 with controls for two separate systems. Left side of the panel is labeled at the top, "Caution Warning System," with 20 indicator lights labeled with warnings for fire, low power, and pressure. Lower half of system has two rows of toggle switches for lighting throughout the lab. Right side of panel is labeled "Refrigeration System," with two selection knobs for display selection, including, "Stowage Freezers," "Urine Freezer," and "Water Inlets." Below the knobs are indicator lights for both the primary and secondary loops, and eight switches for the system pumps along the bottom. Panel retains all of its circuitry and both umbilicals, but is missing the temperature gauge from the upper right. In very good to fine condition, with scattered dings and wear. Accompanied by three paper copy printouts from an internal manual titled 'Orbital Workshop Operational Nomenclature' published by McDonnell Douglas Corporation, dated July 1971 and April 1972, which have the exact layout of this panel plus position maps of the exact location inside Skylab. A particularly early design of an important internal system.
