Black Forest holiday camps

This may be an impossible request.

In the 1960s a small Cambridge-based charity, Children's Relief International (CRI), ran camps in the Black Forest, Germany for boys living in displaced persons camps in Germany. The founder of the charity was the personable and somewhat eccentric Bernard Faithfull-Davies, known as FD. He had contacts (whether formal or informal I don't know) within the BAOR and they supplied the camping equipment, including tents (six to eight for sleeping boys and staff plus a marquee), tables and benches, cooking equipment, three seater field latrines and probably eating equipment and tinned food. This was all delivered by the army to the campsite.

I was a student at Cambridge University in the early 1960s and was the leader of a camp in 1964. Last year was the 50th anniversary and so I've been attempting to find as much information - documents, photographs, memories - as I can about the camps so that I can assemble a short history of an event that couldn't be mounted today in such an ad hoc fashion. Unfortunately, both CRI and FD passed away long ago and there is virtually no documentation of how these camps were organized. So here I am, wondering hopefully whether I have triggered a memory in someone who has some information about these events. Or perhaps someone has knowledge as to whether there is any possibility of records existing, and if so where they might be.
