That's a Nagra IV-SJ stereo tape recorder. It was an instrumentation data recorder, although it works for audio too.
Nagra IV-SJ - Stereo Nagra for instrumentation and logging. Pots are replaced with switches to set gain in precise steps, no limiters, and when present, the microphone inputs are for high-voltage unbalanced instrumentation mics rather than low impedance balanced with T-power and phantom.
