As far as I remember, the P4 panel was the flight engineer's panel on the B727 and the B747-100/200. Been a while though.
That's true on the 747 but I haven't heard to the 727 panel referred to as the P4 panel but I'll ask around. My manual and the Champion manual don't show a P-4 panel, just FE or S/O instrument panel. We just refer to either the P-6 or P-18 panels on the 727.
