There's ANOTHER tough to identify 'square baser' ( big broken one in the last pic )
Has some similarity to a Cibolo but not conclusive, dont hear much about that type. Can you find a complete one so we get a better overall look
That was a fast find ,,,and a beauty too.
We can forget the Cibalo wild guess.
So if it's still up for more guesses, have a look at the Morrill Family.
Surely they made more than ONE Marshall ( that they didn't break )
