Sorry if this isn’t a good place! But if this question is OK, I would be very happy for any information anyone could give.
We were debating whether or not to replace the doorknob. (If we don’t, it obviously needs to be polished.) I think it seems unsafe for an exterior door but would love any additional information. Can’t quite figure out what they would have called this type of lock back in the day, so my google-fu has hit a dead end.
