XJ319, XJ324 & XK895 were all based at Station Flight Culdrose which was part of 771 Sqdn. Station flight always had 2 of the 3 aircraft at Culdrose, while the 3rd would be away for Major Servicing. There may be only one aircraft on static as the 2nd was usually on duty flying VIPs in and out of the show. The aircraft on display is either XJ324 ot XJ895, as XJ319 wa away on major servicing. I have confirmed this by checking the ground running log books that I filled out everytime I ran the Devons, as I worked on station flight at the time. If you give me the exact date of the airday I can tell which aircraft would be flying and which would have been on static. Also XJ319 did not return to Culdrose until Mid October 1988 when it replaced XJ324 away for major service.
