unknown brass item

[Ripcon]

Any clue as to what this brass item could be from? The bottom part is square iron.

Maybe a door knob but the brass piece is two pieces and the other piece came off?

Door knob comes to mind.

Your guess is correct... you found the brass base of an antique doorknob with an inch or so of its broken square iron shaft. You can see those parts laid out in the doorknob-&-latch-parts photo below. The knob and base with the square hole are at upper right, and the square shaft is to the left of the knob.
