Nigel,
I cannot express my thanks to you enough for taking the trouble to repair this beaten up photo of my father in his warship.
I will be sending a copy to the Curator at the Submarine Museum at HMS Dolphin Gosport Hants. (where my father was based during the war), as they did not have a copy of this photo.
I will attach a credit to it in your name for repairing it so magnificently.
Frank
