The installation instructions for the Gainsborough Classic Set show the (2) Fixing Plates are separate from the (7) Knobs and (8) Rosettes. However each Fitting Plate comes connected to a Knob and Rosette and is held in place by a washer. The Knobs appear to be made from some sort of ceramic material.
How can the Fitting Plates be separated from the Knobs without damaging the Knobs?
