I cannot be positive about the Whirlwinds at Gutersloh but 230 Sqn was shipped en-masse to Labuan in 1965. As the only other green squadron, 225, went to Kuching so it would stand to reason that the 230 Squadron aircraft I flew at Labuan in 1966 would be the same ones that were at Gutersloh.
They were: XJ412, XK986, XL110, XP362, XP363, XP395, XP400, XR453, XR456, XR457.
At the end of confrontation the squadron was returned to Europe to Odiham. Some of the aircraft were swopped with the FEAF Whirwinds so the there were some different serials back in the UK.-
