There are a strictly limited number of these parts manufactured, all serial numbered, and it is dead easy to account for them all. You cannot go to the Arizona desert and grab this bit off a scrapped aircraft and float it onto the beach [you maintain they don't float, how do you know?] because there are no 777s scrapped.
If you say there is something dodgy here, it is up to you to say why, not to ask others to prove there isn't something dodgy.
This is the smoking gun, to all who accept logic at least.
Goto pprune.org and the professionals in the industry [I assume that doesn't include you] have no issue with the facts as presented.
