The support leg was made of teak by Hunter's wood shop 43 years ago.
The newer Hunters used the pole method of support.
There may be one lying forgotten in a shed somewhere, but we'll never know.
So, Get a 5 foot long, cedar board approx. 5 in. wide and 1 in. thick.
Why Cedar? Much cheaper than teak!
Take the elevation measurement from the underside of the table to the cabin sole,
(with the table in the 'eating' position). Cut the board to that length.
Decide how much taper you want at the bottom of the board.
Cut down the board to match the taper.
Sand and varnish as desired.
Buy a stainless or brass piano hinge to fit the top edge of the board.
Mount the hinge to the top of the "new Leg".
Then mount assembly to underside of table where the old hinge mounted.
Eat Hearty!
Good luck.
