The Twin Pioneer belongs to 152 and the photo must have been taken in 1962 or later. The squadron flash (yellow white and green) is visible on the side of the nose. In 1960 I was instrumental in getting squadron markings painted on either side of the fuselage roundels of our Pembrokes, like the 152 Sqn Meteor NF14's up to 1958. When I returned to the UK in August 1961 there were no plans to paint squadron flashes on the Twin Pioneers.
