How about Gloster Meteor F8 VZ467 "Winston" - currently still flying in Australia with the Temora Museum? Built in 1949 and only retired from RAF Service in 1982! Operated by several civilian owners in the UK prior to being shipped to Australia and reflown in 2001.
Flypast magazine did some research a few years ago and concluded that this aircraft had a place in history as the world's oldest flying jet aircraft (ie still flying)........
And as a footnote - I used to work on it at RAF Brawdy up until it's sad retirement.....
