Newquay Air became Air South West well before SHH got into the airline business. They had 1 or 2 PA-31's and finished off with 2 Bandits operating PLH-DUB, PLH-ORK and PLH-MAN. They had no connection with the current airline that I'm aware of.
Here is a pic of one of their timetables. I have photos of their aircraft too.
