Dianaa, I hear you. But if I get it wrong you will have to forgive me.
I have tried to change the world as far as Carrier nomenclature goes, but I was already beaten in 1939.
In my further defence, you Aussies are the worst for it! (Blitz)
I remember replacing all the transfer cases because of a design fault, and converting the brakes from a 4x2 to a 3x3 set up.
Sat and passed my heavy trailer license in one, towing the 5.5 gun (with electric brakes) Pretty much had to be on the red line for every gear change.
Another thing I recall, one of the gunners lost his gun in Taupo, on the way home from annual camp. The gun wrote off five cars, and from that incident, safety chains were introduced. Up until then, the Army had an exemption. The Army was lucky, no one was hurt (or killed)
So to say it right, we had Mk 4's, F1s and F2s (they all had the shallow steel hoods/bonnets)

David, thanks for the up date. I did a trip up the Gibb river road (Broome to Kununarra, but we never went up the Mitchel plateau.
From a You tube clip, the air port looks like quite a good regularly used facility.
