Terry, my finding of this extra switch ties in with your comment about the 44RF and 44IF cathodes being tied together on the schematic but having different voltages listed in the tube socket data. Here is what I found; the cathode voltage on the 44RF is 32v with the switch off, 6 with it on. The 44 IF voltage is 6v with it off or on. Again this switch looks factory (same as the 91-126 band switch?) and the wiring is black cloth covered and looks old. The switch on position (far right) makes the radio"come alive".
