Thanks for the information and the reply.
I have the original hard cover version and the later paperback with some updated information on the fatal crash.
I also have a copy of "ARC R & M 1699 Report on Puss Moth Accidents" which refers to an Italian Investigation into the crash. I have been looking for a copy of this Italian Investigation for many years but have not been able to locate a copy.
There is also a book by Ted Wixted called "The Last Flight of Bert Hinkler" which suggests Hinkler was murdered when someone tampered with the propeller of the Puss Moth. I do not agree with his theory.
Thanks again for your reply and helpful suggestion.
