I look into those pics attentively and honestly I don´t see those things as described. I will take a rest and try again. What I like most on Tim s page is a pic of beautiful Amelia aged 16 which I have never seen before... 
I´ve been looking into those pics again after having some rest ( and after I supported my imagination with a few glasses of Pinot Noir

. Being not a Tighar member I´m trying to keep some independent view and this is what I see:
- the circular shaped object resembing something, what could possibly be an old aircraft tire. But it can also be a round shaped block of stone(coral), a big old coconut shell, or whatever else... I´m not saying that it is NOT a tire, but I would say that nobody can be certain (frome these pics) for sure, that it IS a tire. I´m trying to say, that it is not "clear and convincing".
- the object resembling the old style hiking boot. I´m having, however, the hard time when trying to imagine the shoe surviving in recognizable shape in the seawater for 70+ years. Or did they sew them of GORE-TEX in 30ies?
- the rope. it is almost certainly the rope, but it is never a big surpise to find a piece of rope on the sea bottom and this one does not look very old ( to me at least...). I don´t see any grommet and nothing else as the clue to recognize it to be the aircraft tie down rope.
- the other features as described below those pics I simply don´t see ( which of course does not mean they are not there... ). But overall speaking, these photographs are ( in my opinion) far from being clear and convincing to identify the Lockheed Electra wreckage pieces on them.
I apologize if mistakes of my English are too embarrasing, but I have only learned your language at school long time ago.
