2 7/8 inch isn't an odd size, it is simply the OD of any pipe
of "2 1/2 inch" iron pipe size.  Could still be structural,
but might be water pipe.

After fooling around with irrigation pipe, it becomes very
clear that diameter trumps wall thickness and alloy.

Another advantage of a large diameter is that greatly
increased stiffness, something like 3 times stiffer for
3 inch vs 2 inch.

Also, probably less trouble with mast slippage too.
