Do contact me if you wish David. I have lots of info. + pictures re 'Piorun' [used in my recent book] She was famous in the hunt for the 'Bismark'. I have a dozen or so jpegs from the collection of the late Frank Grams, bosun of P. For 'education' use I could send you some 'Piorun' material if your family are interested. If your family would agree it would be great to send copies of your photos + painting (it's story??) to the Polish Naval University in Gdynia. I will present what I have collected to them - ack. the original owners. No problem if for historical/non profit and reseach and/or education.
