Bad editing on my part. The archway soldier is carrying a pith helmet in his left hand. I appreciate all your efforts, I too find a lot of fun in the chase. But the other military pics are landscapes, certainly nothing distinctive. And the family are just more of the same faces against hedges and walls. If no-one recognizes Grandpa I think we might be finished. I've added a couple more pics - looks like the officer's hands are bandaged! Thanks to everyone for your efforts.
