Did my Twin Conversion in the Sea Devon - the RN's Dove - in the summer of 1968 at Lee-on-Solent with 781 squadron. What a nice aircraft!
Don't know when the Navy stopped using them and Sea Herons (had one ride in that too), they ran a regular schedule around the UK Naval Air Stations twice weekly. Known universally as the Clipper.
Very smart livery, white top, dark blue line above the windows and silver below, with Royal Navy in blue just above the line, squadron crest on the fin.
Only snag, my instructor and I were both big guys - the cockpit doorway and the main spar would certainly have hampered a sudden exit!
Good memories,
Mike
