Nutloose I think you are correct, I can remember there were two transducers in the nosewheel well, an S and P-S for altitude, airspeed and mach data to the ADC. They had Pitot and Static feeds of alloy tubing routing direct to them. The feed also went to a pressure switch up in the engine intake on the port side. Can remember an access panel right where the bifurcation was in the intake. A pain in the ass to work in there I can recall. Which means the static ports I mentioned previously only fed the standby instruments in the cockpit ? Memory check time . .
