Malayan Airways seem to have had 13 DC-3s overall. Many got re-registered, often more than once, as the country moved into independence and Singapore split away, so a bit complex.

Most of this info from Air Britain's "The Douglas DC-3" by JWG Gradidge, published 1984. I've put the birdie names on as well for those who remember them (they look surprisingly British).
Nearly 25 years of service, obviously gave good value for money.
Several of the ex-RAF ones were long-time South East Asia residents. My father flew them in Burma in 1944-5 so some of you guys probably were handling the same throttles.
