the only thought on this tool to mutilate threads back then would ? possibly to prevent people from removing the nuts
to steel the item.

just a thought.

I just checked DATAMP,  on the bottom of the page, it states that you use this tool to mutilate the threads
to prevent them from getting loose.

yes, before lock washers, lock-tite and other locking devises.  (1893)

Yupp!!  We use to use a small chisel to distort the thread just enough to prevent the nuts from backing off...
