Seeing this thread has forced me to dig out this photo and scan it in. Taken in about 1969 it show an 1104 MCU Pinnace? almost certainly taken from a 202 Sqn Whirlwind. I always liked the photo which was on the wall in the photographic section at RAF Leconfield and managed to get myself a copy to remind me of the wet and dry winches I carried out with the Bridlington based boats.
