You are absoultely right. Just had a quick flip through new book on the history of Euromanx by Edwards/Lo Bao and it lists three Atlantic ATR42s and also an ATR72 as being operated for Euromanx at one point or the other. There is a nice picture of G-DRFC taking off from IOM. The "palm tree" livery on G-DRFC was a promotional livery for bmi's Caribbean services from MAN - for sure causing great enthusiasm at LBA where the ATR42 was based.
