This 127 format colour slide shows a group of friends enjoying a chat and a drink in the servicemen's quarters of the RAF Seletar base sometime in the early to mid 1960s. I believe this picture includes an RAF Officer but I don't know if he is the one who took the majority of the pictures in the Singapore series here on Found Film, or if he was a friend of the photographer.
This picture seems to have been taken at Christmas time because I can see decorations and Christmas cards on the wall (or possibly window) behind the group and what looks like a present on the small table between two of the men. The room decoration is typically 1960s with the colourful carpet and curtains.
