660 Sqn at Sek Kong was initially issues with Gazelles in 1975-1976, but these were returned to the UK and replaced by Scouts. Maybe the Gazelle was found to be unsuitable in the Far East?.
32 Sqn had (at one point) 4 Gazelle HCC.4s.
There were a pair of Gazelle AH.1s with 8 Flt at Credenhill in the late 90s.
