The large registration of the Dragonfly above is a bit confusing in modern day terms - the airframe registration is not GJ710 but WG751 and the latter is in very small typeface further aft towards the roundel. GJ refers to the station code of Gosport and 710 the side number allocated within 705 Squadron. The size and style GJ710 is however perfectly correct for the 1953 era.
Had my first helicopter flight in a RN Dragonfly....
