Have a talk to Scotty Pringle at YSBK, he does a lot of assembly of aircraft out of containers.
You will now find him where Winrye used to be, north east part of the aerodrome.
Good bunch of blokes.
Tootle pip!!
PS: If you assemble it on the G register, you will need somebody with pommie licenses to sign it off.
I don't think there is anybody in n/nw NSW with a delegation to produce a C.of A.,so you would have to fly one in, but there is in Sydney, Dines Aviation Services P/L is one.
