Yep. 358. Like most of the SD squadrons in Far East Command there's very little written about them - and as 358 only had an operational life of less than a year there weren't that many people around to tell the story.
It was a multinational squadron, with crews from all over the Empire. Technically it seems to have been ultimately under Canadian command: personnel were mainly British and Australian, but there were a few Canadians, New Zealanders and other nationalities too.
They specialised in really long-distance flights: my late father was a navigator with 358 and I still have some of his maps showing flights deep into Cambodia and Viet-Nam. Trips of 23 hours were not uncommon.
