The aircraft in the photos is a T.5 Trainer version and has an interesting history. Seen at Oshkosh, it was originally the prototype Gannet T.2, WN365. It was converted to T.5 specs by Fairey in 1959, with a more powerful Double Mamba 101, developing 3,035 shp. There were no external changes between the T.2 and the T.5.
There are further photos of AS.1 Gannet XA434 of the Royal Australian Navy that is on display at the Museum at Nowra in Australia. This RAN Gannet is one of the 33 AS.1s purchased by Australia in 1955 for their Navy from RN
stocks, and as such they continued to carry their RN serials.
