Comet 4

I've been stewarding the Comet while Concorde is refurbished.  It's a lovely old-fashioned airliner and people are delighted to be allowed access.  The Comet is crewed by two pilots, a navigator and a flight engineer.  It has an autopilot (the black box at the bottom of Pic 4) and a Machmeter (bottom instrument on the left of the central panel).  The engine instruments are very basic - just an rpm gauge  and an EGT meter.  There is no APU - power comes from four engine-mounted alternators, as on Concorde.
