These were found jammed in the beach coral on either side of the landing channel on Nikumaroro during the recent expedition. Look familiar? Them Electra wheel covers sure do get around.
I would love to identify them, but I'm stumped.
They have to be from something quite commonplace on boats or ships.
I have the feeling that some sailors knew exactly what they are and identified them for you.
I tried Googling "aluminum fishing floats," but didn't see any likely matches.
Something associated with fishing nets? Parts of buoys?
Flange for a stove pipe or drain pipe?
Something from the tuna fleet?
I give up!
