EI-ASW
It looks like this Jet Ranger might have been the first B206 to have been operated by Irish Helicopters Ltd, albeit on a leased-in basis.
According to one source, it looks like it was operated by Helicopter Maintenance Ltd, Irish Helicopters, Welltrade Ltd (01 Dec 1968), and then went into private ownership on the 23 Nov 1970. It was cancelled in September 1972, becoming G-BADS before going abroad as SE-HGH and was written off while carrying this registration in 1977. Two different sources confirm these registrations as being correct for this airframe.
