The 707 did not have rudder pedal steering, only the tiller or little half wheel to the left of the Captain's seat. The 727 had rudder pedal steering, but only 5 degrees left or right. For tighter turns you used the wheel on the left. In the event of system A hydraulic loss, the nose wheel on the 727 would caster. The 707 would caster too if hydraulic loss, but I seem to remember helping it with tiller in the direction of turn to allow fluid to move through the steering cylinders.
