S251, if you go to the `nmbva` site and hunt down,eventually you find a listing of where burials took place,then about 1975 ,various locations changed,abd bodies reburied,cremated or repatriated.F/O Smith and SAC Evans were buried in Kranji.F/L Canham ,SACs Langley and Galbraith were either repatriated,exhumed/cremated ,but no date specified when this happened.Hunt around for page 87 on the Roll of Honour.Sorry,but can`t help further,but the CWGC may be able to tell you more info.
