A long time since I posted!
I found these slides but couldn't make out what was on them until I scanned them into Photoshop and lightened them.
This is my Brother and his son, I think it might be the Devon or Cornwall coast, I can see the sea in other slides - I'll have to write and ask him. I have the twin to the jacket he's wearing. Eileen, his wife, gave it to me on my way to Turkey and it really saved me from the bitter winds from the Sea of Marmara, while I stood and waited for my bus that took me to Karamürsel several times a week.
