Hi Andrew,
Thank you very much for that information, that has cleared a query.
I cannot really tell you a lot about Dad's friendship with Freddy Potts. I know that he was quite upset when he died, but I have no idea how the friendship came about unless unless ... Dad was in the Home Guard, so I wonder if Freddy was as well? I think that it would be quite likely, but would not explain why we found that photo in Dad's effects a good few years after Dad's death. Unfortunately I am the only one left of our immediate family, so there is no chance of asking any one.
His bravery was always held up as an example to my brother and myself although I fear that I was too young for it to make much impression on me. It was not until later years that the enormity of what Freddy did to earn the VC actually struck home.
