Marek, I've been to the RAF Museum ay Hendon a few times. I did get some pictures of the Stuka, but if I still have them, they will be on 35mm tranparencies (slides) which I am unable to copy or scan. I have never seen the aircraft with the engine cowlings open to display the engine, but I may have some pictures of the engine of a Stuka in another book. I'll post them if I find them.
Terry.
