Air Ecosse: loads of Bandits, I think they had a Twotter, SD330, SD360
Peregrine: C404, B200, JS31 (first operators of?), GLF1 - I'm sure in the mid 80s Peregrine had, or had use of, a Learjet.
Aberdeen Airways: I think was the scheduled arm? of Peregrine, memory bit hazy now! Had the GLF1s BMPA. BNCE, BRWN (one more?) & brought in 748s also - I recall BFLL (Limping Lil I think someone termed it, Danair days!!) & one or two more. Went belly-up 1991-ish.
