Spent some time on them in the early '80s when Airlines of Tasmania bought most of the airworthy ones. CLT,CLV,CLX,CLZ, can't remember the rest. KAM as well for a while.
They did the LT-FLI, LT-WY-KI runs twice daily and LT-HB newspaper runs at 3 am.
I can attest to their deficiency in icing conditions having seen the fabric peel from the trailing edge of an aileron on a particular flight. (Ailerons, elevator and rudder were fabric covered).
Operating the electrically driven constant speed actuators was an art in itself to avoid the thing sounding like it was about to fall out of the sky as everything went out of sync.
Departing without the required pressure in the accumulators made for interesting gear up sequencing. (and the danger of the gear not coming up if an engine failed)
Lovely old aeroplane.
