Prien and Stemmer don't mention the pilot. Here is a note from their book ("Jagdgeschwader 3 "Udet"..., vol. I, Stab nad I./JG 3..., p. 414):

19.09.1943. 3./JG 3; pilot NN; cause: aerial combat, crashed Loon-op-Zand, 100%; Bf 109G-6, W.Nr 20466.

And:

"[...] 3 Staffel lost one Messerschmitt shot down in air combat near Loon-op-Zand on the Dutch coast. The aircraft's pilot was able to parachute to safety". (ibidem, p. 244-245)
