P2-DEQ was originally restored by one of Col Pay's LAMEs in Scone and then he died and Malcolm Wigglesworth bought it from his estate and imported it to PNG - he was the boss Vet with DPI. He sold it to Colin Cousten, and then bingled it in Western Province - Col exported it to the UK where it was rebuilt and flown for some years before being sold to a South Island Farmer in NZ where it now resides and is much loved - and much missed by Colin (and me) in the UK.
A mate in Brisbane owns a 1971 A36, VH-FMY. The only operator of Bonanzas in PNG, that I am aware of, was Macair (the original) which makes me wonder whether its not the same aeroplane. I'll ask Dave whether his machine is ex PNG.
