The published histories of the Trent Meteor (EE227) suggest that it was Struck Off Charge in 1949, without explicitly saying that it was scrapped at the time.
So it's possible, I suppose, that it survived for a few more years as a Navy instructional airframe.
Edit: However this post on ARRSE Whats this, any plane spotters in? suggests that it was demodded in 1948 before being scrapped the following year.
Either that, or some FAA engineering apprentices were having a laugh with a bog-standard Meatbox and a couple of gash props ...
