Bob- My table uses a "Springfield Marine" leg, it is 2-3/8 diameter heavier aluminum and tapers to 2-1/4 at the socket. Dealer had thin metal legs in various lengths that were crimped to taper. I found Springfield legs here- may be what you are looking for.

Some twist to lock, some have lock pins, mine are tapered both ends and push into socket.
hope this helps
