I was based in Ceylon (Sri Lanka) from 1956-1957, stationed at RAF Negombo (Katunayake) and later at China Bay (Trincomalee). FWIW your mention of Nuwara Eliya on Photo No.9 brought back memories, because Nuwara Eliya whilst I was in Ceylon was an RAF R&R station, high in the mountains. I never got to visit it, more's the pity, but after a certain time at sea level one was entitled to a week at Nuwara Eliya to enjoy the relatively mild climate high in the mountains.
Thought you'd like to know.
