1991 and 1992 at Glasgow. Must have been right at the end of its life.
Had a way to go. Air Toulouse bought its Caravelles (which were several P&W-powered 10B3s) in 1991-2, then slowly ran them down until the last one was withdrawn at the start of 1997. Of course, they would often be no longer used in service well before the official withdrawl date and hand-in of certificate.
As ever in France, one of their fleet (originally new to Sterling) is still around, preserved at what was both the airline's home base and the aircraft's manufacturing plant.
