Haven’t managed to locate the Beaufort COI papers yet either.
Have copies of the files on all 5 crew members.
I am researching three defence force aircraft that crashed within a few miles of each other.
Fairey Firefly WD869 that crashed on the Barren Grounds escarpment above Foxground (just south west of Saddleback Mountain) on the 19 March 1957, 2 crew perished.
Will let you know if I manage to locate the Beaufort missing documents.
