Treaders is correct: it was in ASA livery.
Sadly I have no photos of the ‘8s but I’ll look into some old stuff - I’ve got quite a few of the ‘44s. Mostly down route though and not at STN.
ps I think the 2 TMAC DC-8s (G-BFHW and G-BTAC?) were ex KLM (-54 series, definitely P&W powered) but I’d always thought the ASA liveried one was ex Alitalia.
