Very nice decorative antique brass doorknob set with matching back plates and brass and iron mortise. Fresh out of a Philadelphia Mansion. The mortise is marked Reading Hwd Co. Jan. 1883.  The set has a great naturally aged patina.  The mortise does function with the knobs, Spring is a little weak, the other two mechanisms do not seem to work, we do not have the key, someone drove a screw into the corner of the bolt to stop it from being used, long story short you may need to do some rebuilding, but this was working in the house at time of removal. Both knobs set screws are removable. The lock cylinder is missing. Overall average Salvaged condition. Please be sure to look over all of the pictures as they are the best description. Feel free to ask questions when needed. Thanks for looking!
