My very first job out of high school was dispatching for the Kershaw County (SC) Sheriff's Department. Their base looked a lot like this one with the same microphone as pictured. These cabinets were often customized for the needs of the agency using them. The one at KCSD was not an actual radio, but a control head for the radio which was located about ten miles North of Camden at one time and later moved to the water tank behind the Court House. Our unit like this one had the volume but no squelch control. In the topmost grey panel was an electromechanical digital clock. There were two spring-loaded switches along the bottom panels. One was a "reset" button for the 2250 Hz tone burst decoder (which was mounted on the back of the control head) and a "monitor" button which allowed monitoring of the channel if the reset button had been hit. All cars had a 2250 Hz 1/2 second tone burst encoder on them, which tripped the decoder on the base unit when they keyed their microphones. Ours did not have the green light but the red Motorola "M" would light up when the desk microphone was keyed. Thank You for posting this pic of this grand old radio or control head. They really do not make them like this anymore, sad to say. Wish I could get one operational set up for 2 meter or 440 MHz ham use for nostalgia's sake.
