    Agreed.
    Iíll have to think about how it might be used, but I would cherish it.

    That's what I was thinking. Looks like Acme threading. I'll bet there's more wear on the bottom side of those threads.

    Book press, veneer press...

    (Can't see enough of it to determine the thread form, but my first guess is square or maybe a buttress thread)

    Whatever it is, it is almost certainly meant to apply force in one direction only; against the flat face.
    That's a pretty substantial screw diameter, maybe three or four inches. If used to pull against the tiny fasteners in those wimpy tabs, it could easily break off the tabs or break the fasteners.
    As mentioned, some sort of press could make sense, or it might be the lead nut in some sort of elevating mechanism such as for a large drill press or mill table. Acme threads and square threads are pretty commonly used in such applications.
    I'm thinking it's more likely some sort of bronze alloy rather than brass.

    My first thought, but a 4" steel screw? Probably not...

    Part of an old school printing press or book binders press?
    It really is quite difficult to build an ugly wooden boat.
