The real XG766 was indeed coded 808/NW in service with the RAN at Nowra between 1963 and 1970, but that aircraft eventually found its was to private buyer in South Africa via the UK. This is actually XG770, delivered to the RAN in 1959 and sold after service as 802/NW, 809/NW, 871/NW and 981/NW to a private individual who gifted it to the Australian War Memorial. However it never left Nowra and was later given to the Museum.

This Sea Vampire is not what it seems! It is really XG770, a British-built aircraft delivered to the RAN in August 1959. After navy service it was sold to a gentleman who gifted it to the Australian War Memorial. With no wartime service, the AWM didn't take delivery of the aircraft and it was subsequently given to the FAA Museum. At various times it has been displayed wearing its own serial, XA101 and, currently, XG766.

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.

Built in 1955 for Royal Navy. Shipped to Australia in 1957 serving 724 Squadron RAN. Allocated serial N6-770. Preserved in the museum at Nowra.
