MPN11 did you ever get to Penang/Butterworth?
I think the Australians had taken over Butterworth by the time of your posting to Singapore.
The 'rovings' drove up to Penang for a holiday in 1958.
A visit to the snake temple was fun but the highlight was a trip in RSL1654, which included a stop at a small island. I recall the fishermen standing in shallow water pulling in the fishing nets and there being great excitement that the catch included a small shark.
