Well, I'm not quite that old (even though, as I'm sure you know, 230 never flew either of those types)!
It was Pumas (those plastic helicopters that folk said "will never last" - ever since 1971). They were getting a bit tired in 1979 when I first flew them but seem to have "settled in nicely" since their "end of life update".
36 years ain't bad for a plastic cab!
P.S. Bill Parry, one of the crewman I went through the OCU with, started life as a flight engineer on Lancasters!
