I also have several other locks in the house that look a bit different and I will take them apart, photo them, and get your feedback. Plus, I have a double HUGE pocket door that the previous owner took the locks out and put DOORKNOBS in the pull holes!! Now you can’t open them all the way and the knobs bang into the black walnut casing. They slide beautifully, like the day they were installed. Great workmanship in the original parts of the house but the refurbs in the ’70’s and ’80’s were horrible!
