I remember seeing one of the Princesses cocooned in East Cowes in the early 60s.
Wonderful anecdotes about Dick Stratton, the Princess flight test engineer, here:

I remember him asserting that he held the world record for the greatest number of in flight engine failures at one time, I think it was six, from his days on the Princess.
