Steph. Here is a photo of ORP Piorun being prepared for the Normandy landings. The censor has scratched out the ships number.
Here is a link to a part of the ships war record.

I particularly liked the anecdote about Piorun attacking the Bismark: Just when he was about to open fire, the Captain of Piorun signalled the Bismark
'I AM A POLE!'
