Shawline
My knowledge of Shawline is pretty limited too. A base at Brands Hatch, and they closed down very soon after delivery of Squirrel G-BGCW.
According to their advert of April 79 selling up the fleet they had: 2 B206, Hiller 12, the Squirrel (only 24hrsTT) and a couple of ex RAF Whirlwinds. I think one of the B206s was G-BAUM. They also had a Bell 47 (G-BFPP) at some stage.
