OpsSix you are correct ! (well, almost). My anorak records show SE-DPM (clear enough if you zoom in on the nose gear doors), so where I got SE-DPX from, which never flew in these colours, I've no idea. SE-DPM became G-CEAP the following month then G-IOIT.
SE-DPM 30/5/94, 3 days after cancellation from the UK (G-BEAL). Still of course wearing basic Caledonian colours.
