Noor,
There are no sources available to research the issue of the GSM with clasp "MALAYA" other than the published medal rolls on line.
The Manchester Regiment enlistment books expired c. 1947, before his series of numbers commenced in 1950 so they cant help.
The Regimental Archives dont have any other records to trace individuals.
There are, however, gentlemen on here who served in malaya and may remember him, but I am not one of them.
