Wellwood and Fallon came up to TPNG in 1961 about the same time as I did - but I never shared a posting with them. They must have been in Hagen later in 60's when I was in POM.
Don't know Crawley.
TAL's crew in Hagen while I was there included Peter Hurst, and also Colin Hey was often there ex Goroka. Met Colin in the 90's when I began doing BFR's for the Beverley Soaring Society tuggies. A small world in GA.
happy days,
