I am afraid that Warsaw Concerto and Dangerous Moonlight are virtually unknown in Poland. I am not sure if the film was ever shown or aired here. Such things were prohibited for quite a while, and now they are forgotten, sadly.

Kuryłowicz had a lengthy, dramatic and tragic life, as you probably know and passed through a number of squadrons, including 316, indeed. I know nothing on his post war life, but that he was in the RAF and died tragically. I would appreciate if you can add anything.
