an automatic ejection system posible in wwii

That would have needed some kind of advanced flight computer I think.
Not quite something that was present in WW2

Back then it was best to rely on the best flight comp available, the pilot.
I believe this technique, pulling up, and pushing the stick with your feet, was the most used by all pilots that ejected successfully (alive ) in extreme conditions during WW2.

Just build the aircraft split down the middle and held together with a hinge in the tail and a pin in the cockpit. Pilot unfastens belt, pulls pin and the fuselage is pulled open like a clam shell by the air flow, inertia keeps the pilot moving forward and clear of the aircraft.
