Nick B,
I had hoped an ex-Andover man would come up with the name you are looking for - But I have a vague memory of a 'Hamish' on 52 at Changi when I was there on 48 ( Hercules ) and the surname I think was Raynham.
I possibly remember him because his 'Jizz' suggested he was an Army man rather than RAF.

Good to see you are still 'On the perch'!. I had a long chat with 'Lou Scannon' on Friday, who said he had lunch with you recently.
