I was kindly given a ride in an Army Air Corps Beaver while stationed at Kuching '64-65. Quite a noisy trip as the RH rear door was removed for our maildrop /emergency spares aerial delivery, the latter item being dispatched under a 'hand made' (bodge) chute.
The drop zone was a chopper landing pad somewhere out in the sticks. Both drops landed on target. The spares delivery drop (a radio cable IIRC) was carried out from just above treetop height - great fun, and very accurate!.
The actual aircraft was XP820 which is at the Historic Army Aircraft Flight at Middle Wallop.
