Continuing to dig through the archives.
From
Flight in January 1973 we have a report that the Irish Defence Estimates for the year included provision for six Macchi MB.326s to replace the Vampire Trainers. Instead in April 1974 it was announced that six refurbished Super Magisters had been ordered from Aérospatiale for £1 million.
There was also provision in those Estimates for a medium-lift heli, likely either a Commando or a Super Frelon, to supplement the three Alouettes. That didn't happen and by 1975 interest had turned to the Puma or Bell 212, with the Puma preferred. But by 1979 they
still hadn't bought anything so for the Pope's visit the Garda wet-leased a Bundesgrenzschutz Puma ( SA.330J D-HAXQ cn 1549 )
