Andrew Dodwell discovered this photo of his father, Bernard Henry Dodwell, with fellow players.
He could only identify the sportsmaster, Ron West, in the centre, but the others remained a mystery.
Andrew, who lives in Thame with wife Rosalind, said: “My father fought in both world wars and survived. I’d like to know what happened to his team members and whether they or their relatives are in the area still.”
Bernard, who grew up in Long Crendon, married Angelina Messer from another local family during the Second World War.
Andrew said: “My father was very athletic. I remember him telling me that his teacher had said if he was half as good academically as he was on the sports field, he’d be very successful!”
If you think one of your relatives is in the photo, Andrew would love to hear from you on 01844 212060 or by email firstname.lastname@example.org
