no wessex in brunei - check wiki
I have checked, two built. Brunei Air Wing - check Wiki -no trace.
Wiki is wrong about the Brunei Air Wing. I remember the first Wessex for Brunei transiting through RAF Changi in about 1970 because it overnighted in 110 Sqn's hangar.
Not that it matters. The only time that the RAF and Navy were out there together was during Confrontation and Brunei sub contracted Worldwide Helicopters then.
