That last photo brings back memories of my first flight within PNG - Port Morbid to Samarai on the "Sunbird Service" Catalina. Must have been around 1963 or 1964? The old girl sat at the amphibian base for a long time until sold to Bill Chapman's museum for a reputed one shilling.
I heard it ended up in New Zealand and is flying again?
Last I heard McChook moved from Queensland to Tasmania and is not well.
