Well, at the age of 15, we were rather more keen on the aircraft in those days, so I wouldn't know, Lordflasheart. I can't even blame the failed memory on alcohol-induced amnesia, either......
However, I've had a look at my original photo which is only 3" square and there is a pale-coloured rectangular 2-storey building with a shallow-pitched roof, set in a grove of trees - reminiscent of a country house or grange, perhaps.
I assume the WRENS were kept well-segregated in those days.....
