I agree with you Nev that rear seat flying in the L4 was weird, when taxiing, visibility forward was non existent so zigzaging was necessary, my rudder pedals were on both sides of the front seat, not good with a large passenger, I also had to ask the passenger to move their head to one side on landing so that I could read the instruments. Prop starting was no problem because my regular passengers were pilots so I climbed in the back whilst they prop started then jumped in.
I only ever flew the aircraft from the front seat on one occasion, with a rear passenger, and found it very cramped with my knees up against the dash panel.
I believe that when the aircraft was restored in Manilla the front seat may have been positioned more forward to give more room for the pilot in the rear.
Bearing in mind that the military L4 would have more leg room in the front (pilot) because the observer in the rear would be facing the rear so his legs would go under the 'parcel shelf'.
In spite of this, with the clear Perspex over the entire cabin area visibility was excellent when flying inverted.
