N6-770 caught in the transition from its Royal Navy serial of XG770 to its Australian serial of N6-770. The Australian Navy Fleet Air Arm had since its inception kept the RN serials with which its largely British acquisitions were delivered. This was despite aircraft being allowed an "N" prefix. But the switch to US aircraft in the form of A-4 and S-2s led to a late adoption of Australia serials on the some of the surviving Sea Venoms and Sea Vampires. They were all gone by 1973. -770 was sold but never left Nowra, and is now displayed as XG766 at the Fleet Air Arm Museum.
