S.E.A. Helicopters Sdn Bhd
I visited a friend of mine who was working for this organisation once way back in the early 70's when they operated Bell 47's from Sungei Besi airfield (which is still operational despite being surrounded by the suburbs of Kuala Lumpur). I believe their contract was with the RMAF but was relatively short-lived due to 'contractual' problems. I remember that a lot of the instructors were Amaricans. Sorry, can't be more helpful.
