You are definitely giving your age away! IIRC Whirlybirds was late 50s
and the machines used were Bell 47G 2 seaters (includes pilot, paint
first before assembly). Similar machine to the Sioux used in MASH.
I remember "Whirlybirds", the copter looked like a bubble with a tail
made of girder type structure.

That's the one!
