Yes, it was Jim Blume. I sold it to him in the late 1970s. I think the price at that time was around $9,000. Talair sold maybe four or five C185s.
New Tribes Mission at Goroka also bought a C185 from Talair.
Another went to an Air Niugini pilot.
P2-SEP was retained and eventually restored and repainted (in the original TAL scheme) at Flight West in Brisbane. It is currently in New Zealand, possibly being rebuilt after yet another bingle or so I heard.
It was at a time when Talair was transitioning our of single engine aircraft due to their propensity for gravity to take over when the noise quit, and the airline transition into turbine twins.
Too long ago, I don't recall the details.
