I know this is a strange request, but you seemed to be the most likely people to have an answer.
I visited the UK in summer 1982 and was taken on a day trip by car by an acquaintance. I think we visited the south coast, where I took these two pictures. I have no idea where this is. A friend suggested Lulworth Cove, but I'm not sure. Bear in mind my pictures are over 30 years old.
If you need a high resolution version, contact me and I can arrange something.
Thanks in advance, Ken
