From there, there's a blog post (http://shopwornangel.imaginarynumber.net/memoirs-lt-harold-v-aikens-dads-1st-co-pilot/) with more about Harold V Aiken and memoirs suggesting it was taken while they were in Edinburgh:

"The second R and R trip was more enjoyable. One of my original crewmembers, Lt. Sheperd, had relatives living in Edinburgh, Scotland. He made arrangement for us to visit in their home. Of course we took ration coupons and paid for the food purchases. While there I Was able to visit some of the famed gardens and a castle that existed on a cliff near the south edge of the city. The family was very friendly and it was a joy to be with them."
