Sandisondaughter 15 Sqn
There is a very fine reference book, "RAF Squadrons" by Wing Commander C G Jefford that gives details of location and aircraft operated by squadron and dates. I've had a flick through the 2nd edition and all the activities of 15 Squadron are listed. Forgive me for not copying it in, it is rather lengthy and detailed.
Interestingly, Jeff Jefford was my course commander at 6 FTS RAF Finningley in 1973 on Nav school. A fine chap who also drew excellent aircraft.
Good luck in your searches.
