I believe that may be a tool used by a dentist, or perhaps a family doctor or veterinarian. Perhaps you can research the house and see if a medical professional lived there. If you do a google image search for "antique dental instruments" you'll see quite a few tools which look similar.
While I have aimed in my postings to be irenic and conciliatory, rather than polemic, I have yet endeavored to set forth the
truth, let it favor or impugn whom it might. Any notice of misrepresentations or mistakes occurring in these prose will be most thankfully received
by the author.
