First I wish to appologise for getting my so called facts all wrong, I have just spent a great deal of time on the phone to my dad quizing him for info.
Then I would like to thank you for such prompt and informative replies.
Now for the info,Grandad was born JAN 30 1898 died NOV 17 1968. His full name was "Alan Illingworth Meacham". His Airforce parafanalia was donated in the last year of his life not after his death as previously stated.The museum was in fact the "RAAF Association Aviation Heritage Museum" in Bull Creek Western Australia. The donations were made to Mr Frank Purser (now deceased) I'm told the museum was just founding at this time.In addition to the propeller there was an altimeter, wing struts, a flying jacket, log journals and a letter he wrote to his mother "Florence Peploe Meacham" whilst flying from one place to another whithin England.
In reguard to the photo albums there were five in total two were donated to the museum and three were retained by my father. Not long after Frank Purser approached my dad and requested to borrow the three albums so that an American Air Force Historian (name unknown) could reproduce them in order to aid his research. The albums have never been seen since by theyre rightfull owner.
When I learn how to scan them I shall attach the few photos that I have I mentioned in my first letter, one shot is of the plane showing clearly the modifications described, one of the cockpit and the rest of the model and its inscriptions.
P.S. I can spell Fremantle it was a typo besides locals call it "Freo". Thanks again Philm.
